COMPUTING THE SOLUTION

For large stress values this model is very nonlinear and needs a lot of solver steps to converge. Thus you need to increase the default number of allowed steps before solving the model.

1    From the Solve menu select Solver Param et ers.

2    See that the Analysis list has selection Static and the Auto select solver is active.

3    Go to the Stationary page.

4    Type 50 in thc Maximum number of iterations field.

5    Click OK.

6    Click the Solve button on the Main toolbar.
