Altair SimSolid makes the process of finding modes much easier. Structural analysis with SimSolid's speed and accuracy - as independently validated by NAFEMS - provides the ability to analyze large assemblies and complex parts. Altair SimSolid calculates modal participation, effective mass and cumulative mass factors for each mode in a specified global or local coordinate reference frame. There are many “rules of thumb” of how many elements, etc are required. Complicating this further, many modal eigen-solvers are sensitive to the kind, size and shape of the elements used. Solution times for all analyses are relatively fast – even the largest ran in under 4 minutes. 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. You may unsubscribe from these communications at any time. A modal analysis is used to find the natural frequencies along with the corresponding shape of the structure at each frequency. Simplification of the geometry is common to make meshing easier, but this can lead to errors if critical mass or stiffness features are left out. It operates on fully featured CAD geometry and does not create a mesh. Modes are sensitive to the mass and stiffness available in the model. Solution times for all analyses are relatively fast – even the largest ran in under 4 minutes. Analysis is all about managing trade-offs between speed and solution accuracy. Total time for First, let us perform modal analysis on this model. With Altair SimSolid there are no solver types or options to set. 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.
