55.6. Analysis and Solution Controls

The following two solutions are performed:

  • Solution 1 (Inverse-Solving Analysis): A nonlinear static analysis using inverse solving (INVOPT,ON) is performed on the hot geometry of the model to obtain the cold geometry (for manufacturing) and the stress/strain results on the hot geometry.

  • Solution 2 (Forward-Solving Analysis): Consider the results of this analysis as a reference demonstrating the correctness of the inverse-solving analysis. The cold geometry obtained from Solution 1 is solved again but with a traditional forward-solving analysis to obtain the hot geometry with stress/strain results.

An inverse-solving analysis followed by a forward-solving analysis, or vice versa, is known as a loop test, as it should always result in the same geometry with the same solution.
