Define the section parameters for use with Simulation Composite Analysis.
When a *User Material definition is used, Abaqus cannot compute certain section parameters because the elastic constants necessary to compute these section parameters are not available. You must define these parameters for an analysis to run successfully.
Simulation Composite Analysis comes with the command line program xStiff that reads an Abaqus input file and automatically computes and inserts extraneous stiffness parameters required by reduced integration elements utilizing Simulation Composite Analysis materials. This auxiliary program significantly improves the speed and accuracy of the model building process.
