I am working on an implicit case. First I applied a load on a group of nodes. Now I apply an imposed displacement. It worked fine for the first one but I get an error in the engine file for the imposed displacement :
MESSAGE ID : 79
** ERROR : RADIOSS IMPLICIT STOPPED DUE TO LOADING DATA **
Here my imposed displacement input:
IMPOSED DISPLACEMENT ON TOP NODES
ISTOP is a keyword to show the error. This error message occurs when no loading has been defined in the model or when loading is zero during the first step in a nonlinear analysis.
Below are a few suggested workarounds for this error:
1.Check loading in the model.
2.Increase the initial time step.
Let us know how it goes!
