My initial experience with Altair SimSolid was positive. Do you think this is true? According to Greg: "Compared to FEA in SolidWorks, SIMSOLID by far gives us more data, reactions, things like that but we were using it within 30 minutes with no training. Onshape vs SimSolid; Onshape vs SimSolid. It inspects complex parts and large assemblies, using theoretical and traditional FEA. Introduction to SimSolid Description . The computational engine is based on Permalink Submitted by ganesh.anandakumar on Mon, 2009-08-31 15:54. ), Welds shown in green. Solution adaptation is based on local energy density change and absolute errors on boundary. Again, the results look qualitatively good, but the results was 7,500 psi for the maximum stress, in error by 27%. Altair has launched SimSolid 2019.0.1, is structural analysis software developed specifically for design engineers.

Components can be selected individually or in groups and forces/moments can be summed to quickly understand load balance and free body forces. Introduction to SimSolid Description . Welch and Apanovitch emphasized that SIMSOLID is aimed at design community users who want fast answers to configuration changes, both within a part and within the overall assembly. Fig.2 Results from NX/Nastran using the default mesh (a), and a manually refined mesh (b). Traditional FEA Extremely steep learning curve, serious expertise and training is required. Will I need to purchase a new CPU (like Xeon) if our FEA simulations will be pretty light, will just a RAM and SSD upgrade suffice? SimSolid Both fast and accurate. Automotive chassis model with welds represented as cylindrical tubes. Runs quickly, accurately, all from an stl export. Remove. SimSolid has been designed to analyze complex parts and large assemblies not practical with traditional FEA.

Compare your results to your traditional or CAD embedded FEA and see for yourself what the thousands of satisfied SimSolid users across the globe have already learned. SIMSOLID = Meshless FEA. For example, the software can increase the geometrical density in an area of interest by adding more geometrical supports. Thanks. ), Complex load paths. That SIMSOLID can handle this configuration is reassuring. The model selected was a welded tube joint. Instead of using a mesh made of regular simple shaped elements it divides the model into arbitrarily shaped volumes. These metrics are quite often a way to see how popular every service is and how extensive is its online presence. “I’ve seen weld modeling go from weeks to minutes using this method,” Welch adds. SIMSOLID capabilities … Engineering.com readers are familiar with SimSolid, which provides an alternative to traditional finite element analysis methodology. XR Lateral reducing the bend angle with less stress and can model how the forces impact the assembly with SIMSOLID. ... test it out on your own models. They said to me that SIMSOLID is not FEA but instead it is an FEM software which doesnt use meshing scheme. To learn more about SimSolid and download a free trial, visit Altair. It inspects complex parts and large assemblies, using theoretical and traditional FEA. Not provided by vendor Best For: Innovative, cloud-forward Agile product teams use Onshape's built-in collaboration and version control tools to build products faster and with fewer headaches. This model was also analyzed with Autodesk Inventor simulation, which has an adaptive automesher that is at least as powerful as those in most commercial FEA codes. This provides the ability to handle geometrical imperfections, as well as assembly contact ... SIMSOLID VALUE (Hz) DIFF vs REF (%) DIFF vs NAFEMS (%) 7, 8 out-of-plane 51.85 -52.29 51.547 0.58% -1.42% 9, … 1. To fulfill the requirements for crash and modal analysis, the company used OptiStruct to optimize the component, RADIOSS and other external solver to run the calculations and HyperView for the post processing. “We get the accuracy, but in much less time.”. (Picture courtesy of Altair. “Users simply need to specify the weld diameter and which parts to convert, or even better SimSolid can examine all parts and propose which ones are suitable to convert. By eliminating geometry meshing and simplification SIMSOLID dramatically reduces the amount of time and expertise required for even complex FEA. We catch up with Welch, co-founder of SimSolid, after the larger simulation vendor Altair acquired his company last October. Fasteners automatically modeled with SimSolid include bolts and rivets. We think of FEA democratization as really three things: It’s got to be simple, it’s got to be fast and it’s got to be accessible. ActCAD. What’s the Difference Between Parametric and Direct Modeling?

Write a Review. All default settings were used. Pretty much all steps are the same as in regular FEA (same governing equations, matrices and solvers) but the discretization step is different. There is also a straight from the user mouth video where a user in oil and gas talks about how he has checked the accuracy. Onshape by Onshape Remove. It’s no fun to get a part or assembly ready for simulation. Both fast and accurate, SimSolid controls solution accuracy using a unique multi-pass adaptive analysis. Numerical methods such as the finite difference method, finite-volume method, and finite element method were originally defined on meshes of data points. Starting Price: $1,500.00/year/user. Conceived to analyze complex parts or large assemblies not practical with traditional FEA, SimSolid excels faced with ragged contact surfaces having both gaps and overlapping geometry.
