Developing a zero-emission, all-electric regional commuter aircraft

By Leave a Comment

Dassault Systèmes announced that the electric air mobility pioneer, Eviation Aircraft, used the 3DEXPERIENCE platform on the cloud to develop the first prototype of its zero-emission, all-electric regional commuter aircraft – Alice – in two years.

In the race to create and commercialize new categories of sustainable air mobility systems, Eviation Aircraft accelerated the prototype’s development by deploying the “Reinvent the Sky” industry solution experience based on the 3DEXPERIENCE platform. This scalable cloud solution supported the company’s holistic approach to 3D, composite design and flow simulation with improved collaboration while securing data in a single, standards-based environment.

“The electrification of aircraft isn’t a question of if, but when. As we aim to make clean regional air travel accessible for all, we needed to be able to make a product that people trust, sit in and fly, and do it quickly,” said Omer Bar-Yohay, CEO, Eviation Aircraft. “The right way to go about it was to use tools that we would want to use in the long run, and to work in the cloud to ensure fast, secure access and global collaboration. When we selected the 3DEXPERIENCE platform, we were an early-stage startup with limited resources and time. We’ve developed our commercial-stage prototype faster than we imagined, and have already signed our first customer in the U.S.”

Eviation Aircraft realized that transforming a prototype into a product that can be manufactured by the hundreds each year would require empowering its engineers with the long-term knowledge and know-how to build it to maturity for the next generation.

Once commercialized, Alice will be the world’s first all-electric regional commuter aircraft, capable of carrying nine passengers and two crew on a single charge for 650 miles at 10,000 feet.

PTC to acquire Onshape

By Leave a Comment

PTC announced that it has signed a definitive agreement to acquire Onshape, creators of Software as a Service (SaaS) product development platform that unites computer aided design (CAD) with data management and collaboration tools, for approximately $470 million, net of cash acquired.
The acquisition is expected to accelerate PTC’s ability to attract new customers with a SaaS-based product offering and position the company to capitalize on the inevitable industry transition to SaaS. Pending regulatory approval and satisfaction of other closing conditions, the transaction is expected to be completed in November 2019.

Located in Cambridge, MA, Onshape was founded in 2012 by CAD pioneers and tech legends, including Jon Hirschtick, John McEleney, and Dave Corcoran, inventors and former executives of SolidWorks. Onshape has secured more than $150 million in funding from leading venture capital firms and has more than 5,000 subscribers around the world. The company’s software offering is delivered in a SaaS model, making it accessible from any connected location or device, eliminating the need for costly hardware and administrative staff to maintain. Distributed and mobile teams of designers, engineers, and others can benefit from the product’s cloud nature, enabling them to improve collaboration and to dramatically reduce the time needed to bring new products to market – while simultaneously staying current with the latest software.

This acquisition is the logical next step in PTC’s overall evolution to a recurring revenue business model, the first step of which was the company’s transition to subscription licensing, completed in January 2019. The SaaS model, while nascent in the CAD and PLM market, is rapidly becoming industry best practice across most other software domains.

Onshape will operate as a business unit within PTC, with current management reporting directly to PTC President and CEO Jim Heppelmann.

Barclays acted as exclusive financial advisor to PTC on the transaction.

Volume Graphics releases new generation of CT Software

By Leave a Comment

–Volume Graphics announced the latest generation of its software solutions for non-destructive quality assurance with industrial computed tomography (CT): Version 3.3 of VGSTUDIO MAX, VGSTUDIO, VGMETROLOGY, and VGinLINE.

VGSTUDIO MAX software is used for the analysis and visualization of industrial computed tomography (CT) data and covers all requirements related to metrology, defect detection and assessment, material properties, and simulation.

Using the new version, customers can determine the surfaces of multi-material components, export measurement and analysis results to store them centrally in quality-management software, automate inspection processes more flexibly based on text recognition, and translate real CT data into volume meshes for simulation.

To further support their customers, Volume Graphics has also added a Technical Consulting unit that provides professional consulting and evaluation services.

“With version 3.3 of our software solutions, we are once again laying the foundation for customers to make their processes smarter,” says Christof Reinhart, CEO and co-founder of Volume Graphics GmbH.

“For example, using the new data export, metrology data derived with the tremendous measurement capabilities of our software can be seamlessly shared with QA systems, where the values can then be combined and checked over time. More than ever before, this new feature enables customers to better integrate leading-edge CT technology into their existing software landscape. The new export feature is based on the native support of the widely used Q-DAS format, which makes using results in third-party statistical or analysis software especially easy.”

An overview of the innovations in VGSTUDIO MAX 3.3: Multi-material surface determination

–A new mode of the local-adaptive-surface determination enables the simultaneous determination of the surfaces of each material within a volume in one go
–This significantly simplifies the geometric dimensioning and tolerancing of multi-material objects, e.g., the position of metal pins of a connector relative to the plastic housing
–The new mode also facilitates segmentation of multi-material objects

Support of native data export in Q-DAS format

–There is now native support for data export in Q-DAS format for both VGSTUDIO MAX and the VGMETROLOGY metrology solution, as well as the VGinLINE solution for automated CT inspection
–Companies that still work with traditional measurement systems can switch to this comprehensive CT measurement technology without encountering software hurdles or having to forego their established processes for further statistical evaluation
–Export of detailed, CT-based measurement and analysis results (coordinate measurement, nominal/actual comparison, wall thickness analysis, porosity/inclusion analysis, fiber composite material analysis) is now enabled in the common Q-DAS data exchange format

OCR-based automation
–New optical character recognition (OCR) allows customers to read out text in CT scans, such as object identifiers, and store the recognized text in their meta information
–In automated inspection workflows, cavity markers in CT scans of injection molded or cast components can be recognized and the right reference object or the appropriate analysis in VGinLINE jobs can then be selected depending on the respective cavity
–At the same time, the recognized text improves the traceability of the results, since the information about the cavities can be included in the reports

 

Volume meshing for simulations
–With the new Volume Meshing Module, users can create accurate and high-quality tetrahedral volume meshes from their CT scans for use in mechanical, fluid, thermal, electrical, and other FEM simulations in third party software
–This is based directly on the subvoxel-accurate surface determination for scanned parts or material samples consisting of one or more materials
–The individual components of multi-material objects are translated into volume meshes with congruent tetrahedron faces and shared nodes at material interfaces
–The complete workflow from CT scan to volume mesh is covered
–Generated volume meshes can be exported in common .pat and .inp file formats
–Each cell of the generated volume mesh can be loaded with additional information required for simulation, such as fiber orientations, fiber volume fractions, porosity volume fractions, or gray values

Backed by 20 years’ experience in industrial CT, the new Technical Consulting unit analyzes the specific requirements of each customer’s application(s), creates optimal software configurations and general CT hardware specifications, and offers complete evaluations as a contract service

COMSOL Multiphysics includes tools to support 5G, IoT design

By Leave a Comment

COMSOL announced the latest advances in its COMSOL Multiphysics software to support microwave and RF engineers working on 5G, IoT, automotive radars and satellite communications. With these tools, designers can model different PCB materials and study how they affect the performance of microwave and millimeter wave circuits. Several of the application examples to guide designers will be introduced at the International Microwave Symposium (IMS) 2019.

“We are particularly excited to demonstrate how to set up and run a simulation to design and evaluate a Grounded Coplanar Waveguide (GCPW) line,” said Jiyoun Munn, technical product manager of the RF Module at COMSOL. “Connectors and low loss materials are the key components across all electronic devices and systems. Their reliability is critical in circuits that transmit and receive information.”

The use of simulation to achieve low insertion loss and reliable circuit performance in a design, requires choosing accurate material properties such as relative dielectric constant and loss tangent, while also considering surface roughness effects in the computer model.
“As the frequency increases, maintaining the impedance become more complex, as small quirks arising from the geometry or selected materials can be magnified,” explains Bill Rosas, Cofounder of Signal Microwave. “Simulation allows us to ensure that these critical pieces of RF infrastructure are optimized for 5G communications.”

Designing components ready for 5G, IoT, automotive radars and satellite communications will require multiphysics modeling. Using COMSOL Multiphysics microwave and RF designers can couple electromagnetic simulations with heat transfer, structural mechanics, fluid flow, and other physical phenomena, allowing them to represent coupled physics effects as they would occur in the real world. That means being able to accurately investigate designs and fully benefit from the virtual prototyping capabilities multiphysics simulation offers.

Software automates the selection of interior or exterior parts in detailed CAD assemblies

By Leave a Comment

CoreTechnologie (CT) presents its latest version of the “3D_Evolution Simplifier” software with new functions. The new selection tool is for digital mock-up and VR applications and helps simplify large assemblies of cars, trucks, planes and trains.


Scope of data as a challenge
For VR and DMU requirements in practice often only the external or internal parts of a very large vehicle assembly are needed. Especially with extremely large assemblies such as trains, aircraft and automobiles, the selection of the desired components or sub-assemblies can be difficult and take a large amount of manual work and time. Even modern 3D systems quickly reach their limits as complete and detailed car assembly needs to be displayed to manually select the desired scope.

Balloon selects the Interior
CoreTechnologie’s team has developed a new voxel-based function for the 3D_Evolution Simplifier software tool. The software tool selects the desired items through a so-called balloon stretching out from a user defined starting point. There is practically no limit to the size of the data. The selection process takes place within the shortest space of time by using multiprocessor calculation. The automatically selected models, which represent either the interior or exterior, can be converted to all common 3D formats.

The software offers direct interfaces for major systems such as Catia V5 and V6, NX, Solidworks, Creo, Inventor as well as standard formats such as STEP, JT, FBX, DWG and DGN. A clever side effect of the balloon calculation is that the contact body consisting of voxels is representing the interior volume minus all bodies contained therein and thus represents the volume of air or liquid inside. Thus, the automatically created model is a closed volume that can also be used for further simulation purposes.

Envelop Geometry improves CAD performance
From detailed engine, gearbox or machine and plant assemblies, the Simplifier generates exact enveloping bodies as solid geometry, with significantly smaller file sizes and thereby guarantees CAD and VR performance with up to 95% reduction in element count. The simplified models represent an exact representation of the outer shell whose inner geometry has been completely removed.

In addition, the simplified shell provides the advantage of sending 3D data, effectively protecting valuable know-how. When collaborating with suppliers, customers or partners, as well as in downstream processes, automatic selection and envelope geometry generation of complex components is an integral part of the PLM process chain, both for the protection of know-how and for the automated creation of lightweight 3D models used for VR and DMU process or for further operations in the CAD system.
