Autodesk NASTRAN IN-CAD 2015Īutodesk NASTRAN IN-CAD 2015 – all up inside SolidWorks Post processing is much the same, using common tools, no matter the solver used under the hood. They use the same study set-up tools, then choose whether to solve that simulation run using the existing, Algor based tools, or using the NASTRAN solver. While Autodesk has had its solver technology from the Algor acquisition for a while, it now offers the user a choice. The manner in which these have been implemented is also telling. What’s changed with this is that users of these tools now have access to the NASTRAN solver alongside the existing methods. It encompasses the Algor-based tools, CFD as well as some additional tools such as Autodesk Robot Structural Analysis for Civil engineering. Autodesk Simulation 2015įor a while now, Autodesk has been reworking its simulation product offerings into a single interface (work that’s by no means complete) and the Autodesk Simulation product is the current state of the art. For those that have already licensed NEi Nastran, this is what they’re most likely to be going after and using either their own home brewed pre and post processor or using a system like FEMAP.

NEi took the base level code and extended its non-linear capabilities. This is a solver level product that’s similar to the raw code that’s been available for some time from both MSC and Siemens PLM. But first, what’s on the cards now? Autodesk NASTRAN 2015Īutodesk’s real time solver viewer – perfect for checking in on a solve or pulling data from those legacy studies The company has launched a couple of different new products and the approach that it has taken is telling. I think it’s fair to say that it has become the de facto standard in the aerospace industry and widely used in most other industries where engineers are looking for robust, reliable code. Not necessarily the large scale OEMs, but perhaps smaller tier one suppliers and smaller companies doing fascinating work, whether that’s in aerospace, automotive, auto-sport or marine design.ĭue to its pedigree it’s one of the few solver codes that is implicitly trusted. That saw the market split into two camps – with MSC.NASTRAN and NX NASTRAN.Īlongside this, NEi has, for some time, been developing its own flavour of NASTRAN (which extends the non-linear capabilities of NASTRAN’s inhererent strength in linear simulation), offering solver level code as well as its own front-ends (with NEiWorks for SolidWorks being the most well know) as well as selling it alongside pre and post processing systems, such as FEMAP from Siemens PLM. In 2002, the FTC investigated MSC and the judgement saw a cloned copy of its NASTRAN code handed over to UGS (who became Siemens PLM). MSC.Software (MacNeal Schwendler as they were known back then) were first in the game and became the dominant vendor. This is where the various commercial exploitations of the code come into play.
What NASTRAN doesn’t do (on its own), is give you a graphical user interface to that process. That means that you have a set of tools that, given the right input data, will solve the simulation task and give you back the results. While the NASA code has always been available to anyone that wants it, commercial exploitation of that code became inevitable. Its development has been interesting – mostly because of the business activities surrounding it – many of which resulted because of its origins at NASA. NASTRAN was developed by NASA (the name stands for NASA STRucture ANalysis) in the late 1960s and early 70s. Now the cat is most definitely out of the proverbial bag. This news first broke earlier in the year, but with the company now only looking to announce acquisitions once it has done something useful with the technology and organisation it acquires, it had remained pretty tight lipped. Last week, the company finally acknowledged that it had acquired NEi and its line of NASTRAN based tools.
Blue Ridge Numerics for Computation Fluid Dynamics.PlassoTech for CAD integrated, basic linear structural work inside Inventor.Solid Dynamics was followed by a pretty consistent streak: Since it first acquired Solid Dynamics to put motion simulation inside Inventor back in 2005, the company has been through a long string of acquisitions to get it to this point. The 3D design giant, Autodesk, has had a history in simulation (for the purposes of design and manufacturing) for nearly a decade and a half.
