Rich set of Loads and Restraints

 

SimWise FEA has a rich set of functional objects that are added to your CAD model to build a functional structural prototype. These objects include:

• Concentrated loads, distributed loads, torques, and pressures

• Restraints and enforced displacements

• Prescribed temperatures, conductive and convective heat flux, and radiation

 

All of these values can be driven by the SimWise formula language. All of these objects are applied to the underlying geometry, not to nodes and elements as in a traditional FEA product.

Solver Technology

​

SimWise uses a fast iterative Finite Element Analysis solver that takes advantage of multi-core processors and which is based on a Preconditioned Conjugate Gradient method. SimWise FEA exclusively uses ten-node tetrahedral elements and the solver is optimized for this type of problem.

​

SimWise FEA can display FEA results as shaded contours, deformed shapes, or animations. In addition to these engineering values, SimWise FEA also calculates factors of safety and errors in the stress results and both of these can be displayed as shaded contours.

Adaptivity refines the FEA model in areas of high stress

 

The error results can be used to drive an iterative solution process called h-adaptivity where the error results are used to refine the Finite Element mesh in areas with large error values and use that new mesh to run another solution. The errors in the new solution are compared to a goal and if error values in the model still exceed the goal, the process is repeated with successive mesh refinements and analyses until the error goal is achieved. Confidence in the results are increased and no special knowledge about appropriate meshing techniques is required.
