simsolid modal analysis

Complicating this further, many modal eigen-solvers are sensitive to the kind, size and shape of the elements used. First, let us perform modal analysis on this model. Future releases of SIMSOLID Professional will also link a modal analysis to a frequency or random response analysis, as well as link a nonlinear static analysis to a modal analysis, to assess mode stiffening. This provides the ability to handle geometrical imperfections, as well as assembly contact imperfections like gaps, penetrations and ragged contact areas. In traditional FEA, finding modes can be problematic. Here is an example of circular steel plate. In this tutorial, we show you how to set-up, run & post-process the finite element analysis of a cantilever beam/structure.

All runs are performed on a standard Intel I7 desktop computer with standard solution settings. Best of all, solution times are typically fast – seconds to minutes, even when asking for large number of modes. KW: Certainly. Structural analysis with SimSolid's speed and accuracy - as independently validated by NAFEMS - provides the ability to analyze large assemblies and complex parts. In SIMSOLID no meshing is required, so the entire process, from FUSION 360 to results, was done in under 10 minutes.SIMSOLID is next generation, high capacity, structural FEA. Modal – Modal analysis in structural mechanics is used to determine the natural mode shapes and frequencies of an object or structure during free or fixed vibration. Have a Question? This mode illustrates the ability of SIMSOLID to efficiently analysis a large assembly with parts of varying size scales (small to large) and varying geometric complexity. Finally, here is a video of modes being calculated on a more realistic model. Improved CAD Integration for SIMSOLID Professional Every incarnation of SIMSOLID is able to integrate CAD. It eliminates geometry simplification and meshing, the two most time consuming and … Q: When creating connections, I get the message, “Last task was completed with messages” and the message reads “Warning: Assembly has XX disconnected groups of parts”. One primary objective of the modal analysis is to make sure the structure is not operating (vibrating) at a frequency close any of its natural frequencies. This is an example structural analysis of a large assembly containing complex geometry done using SIMSOLID. With traditional FEA, the user is forced to understand the strengths of various solver methods (Lanczos, Subspace, Householder, etc) and solvers (Sparce, PCG, etc.). The mesh body has just over 1/2 million facets. For a given structure, there is an infinite number of vibration modes, however FEA modes are limited by the number of degrees of freedom available in the finite element model.
