Click Solve to start the analysis.
We set the number of iterations to 200 to reduce the overall time of the exercise. To run the analysis to convergence automatically, increase the number of iterations to 300.
As the mesh is created, informational messages are displayed in the Output Bar.
After the mesh is completed, the analysis runs.
