Simcenter Samcef UMAT output requests and results

In the Structural Nonlinear Output Requests of the Simcenter Samcef Nonlinear solution, you can define Scalar Result (Samcef x399 family of result codes), Tensor Result (Samcef x499 family of result codes), and Vector Result (Samcef x599 family of result codes).

As classical Output Requests, you can define these requests on the Structure or for a Group of elements. You can define Element Nodal or Element codes.

For more information, see Structural Output Requests User Result Code Selection dialog box (Simcenter Samcef).

In the OVMB*.f routines, you have to set which results these codes will contain (Samcef LSAV data). For more information, see figure 2 in the Behavior routine (OVMB01) page in the Simcenter Samcef documentation.
