I am still writing a book about turbulence. It would be my first book in English. Currently it has more than 100 pages and more than 100 hours have been spent. I will publish some fragments from it here and some practical examples as well.
Germany’s Siemens makes the first big headline of 2016 with the announcement that it will buy simulation company CD-adapco for a whopping $970M.
Siemens PLM is best known in the CAD world as the maker of enterprise CAD, CAM and CAE software, notably NX and Teamcenter, as well as Solid Edge. Melville, New York’s CD-adapco was the last big independent CFD company. The 900-person-strong CD-adpaco was able to boast a 2015 revenue of $200M and claimed a growth rate of 12 percent year over year for the last three years, according to the joint company press release.
With other CFD companies being scarfed up by CAD and CAE companies with bigger ambitions (Fluent went to ANSYS, Blue Ridge Numerics to Autodesk), CD-adapco was the last of the big independent CFD holdouts.
With the death of its founder last year, Steve MacDonald, the reins were passed to wife Sharron MacDonald, whose single biggest act of her short tenure was getting Siemens to fork over five times her company’s revenue.
We didn’t see this coming. CD-adapco had been so public in their affection for Dassault Systèmes at last year’s annual user meeting that our Shawn Wasserman came close to suggesting they get a room. (See “What CFD Software Giant Could Join the 3DEXPERIENCE?”)
Had the competition to acquire CD-adapco set off a bidding war between Siemens and Dassault that bumped up the price? We may never know. However, it has come to light that Bernard Charlès, CEO of Dassault, has informed his troops (in a companywide email, according to industry analyst Monica Schnitger) that paying such a ridiculous price can only hurt their competition.
“Simulation software is key to enabling customers to bring better products to the market faster and at less cost,” said Klaus Helmrich, a member of the managing board at Siemens. “With CD-adapco, we’re acquiring an established technology leader that will allow us to supplement our world-class industry software portfolio.”
Siemens PLM was not withoutCFD capability. NX Flow already did CFD for Siemens’ customers and was fully integrated with other NX products, its enterprise CAD application. It remains to be seen how CD-adapco’s offering will be positioned in the Siemens PLM portfolio.
ESI Group has just cashed in on its previous Ciespace acquisition by officially bringing its Virtual Performance solution onto its new cloud platform.
Users will also have access to an end-to-end CFD solution based on the open-sourced OpenFOAM solver. This should come as no surprise as Ciespace’s flagship platform was a very similar product.
The ESI Cloud itself is being marketed as a secure, reliable and scalable software as a service platform. The cloud will not only allow analysts and engineers to compute their simulations online, but it will also let them access ESI software in the browser.
This allows users to build and model geometry, pre/post process and run their simulations over a web browser on demand. Engineers and advanced users can import 3rd party and open-sourced geometry, meshing, solvers and visualization engines.
The service is currently limited to the Virtual Performance solution and the OpenFOAM CFD solution. The remainder of ESI’s large fit-for-purpose simulation portfolio will likely take some time before it is all available.
The ESI Cloud will also be able to run workflows in parallel, create templates and teach users by offering sample projects. The cloud product aims to increase real-time collaboration between members of the engineering team.
The ESI Cloud is powered by the Amazon Web Service, allowing for scalable high-performance computing (over 32 cores), multi-tenant architecture and an open application framework. Some of the collaboration tools offered by the new cloud service include ability to:
•Work on data, workflows and projects asynchronously
•Have multi-user collaboration in a browser for CAD, geometry, mesh and results
•Create real-time notes, annotations, image archiving and retrieval
•Share and email projects and workflows to teammates and non-ESI Cloud users
•Share results without data transfer
Mentor Graphics Corporation announced the latest release of its general purpose, front-loading computational fluid dynamics (CFD) FloEFD solution. Updated features in this new version include improved mesh handling, an enhanced transient solver, a more robust EDA interface, and an interface to Abaqus Finite Element Analysis (FEA) software for stress analysis. Engineers and specialists in the automotive, aerospace and electronics markets will leverage these updates to help improve accuracy and productivity.
The latest version of the FloEFD product offers new capabilities to help minimize user time and effort spent on meshing. The FloEFD tool can automatically fill gaps of specified size to more quickly make the model watertight, thereby helping to eliminate the time and necessity to adjust the original geometry. The new equidistant refinement capability lets users build multilevel uniform meshes around the body or surface of the model with just one click. And, the mesh preview visualization tool helps users achieve the desired mesh with additional ease and speed.
The new FloEFD product release also features the following:
◦A highly improved transient solver allows for faster solution of transient applications as well as higher accuracy for pressure-dominated tasks, such as calculating filling/evacuating of a tank or water hammer thereby increasing range of realistic situations that can be modeled.
◦A more powerful electronic design automation (EDA) interface can help users avoid creating PCBs manually. Users can now import geometric EDA data including copper traces and vias. The interface supports the Mentor Graphics Xpedition (CC or CCE), IDF and OCB++ PCB design data formats.
◦The refractive index depending on wavelength and temperature offers higher accuracy of light and radiation analysis in case materials with complex spectral characteristics are utilized e.g. in automotive lighting industry.
◦The ability to visualize rays used for precise radiation modelling allows the user to better understand the impact of the sources on the system, thus helping to find the reason of overheating and suggest the solution faster.
◦An engineering task usually requires views from different angles. To support multi-disciplinary analysis, the FloEFD tool can now export pressure and thermal loads to Abaqus for further stress analysis.
◦The Calculation Manager displays all projects currently running and those in the queue, thus allowing users to get a better idea as to where their projects stand and to more easily control all calculations running at the moment.
The FloEFD product is available as a stand-alone and/or a CAD-embedded tool supporting popular MCAD platforms including Creo, CATIA V5, and Siemens NX.
I am re-opening site, and starting to publish everything in English. Hopefully it would soon be transferred to more serious resource about CFD.
