Appendix B - State Variable Outputs

This section provides a list of the solution dependent state variable outputs produced by Advanced Material Exchange. There are a total of eleven state variables computed and updated by the Helius PFA user subroutine at each integration point in the model.

The finite element solver stores the converged values of the state variables in the same manner it stores values for typical element outputs such as stress and strain. A unique file (*.mct) is generated for each analysis. This file contains a complete list of the state variables that apply to your model. The *.mct file is the best reference for understanding the meaning of each state variable.
