- In Tree view double click on the solver object .
- Click on Write file in the same task panel. Watch the log window until it prints "write completed." You can ignore the warning about the vacuum permittivity that might appear.
- Click on Run. Since this is a small analysis it should take a few seconds to run so wait till you see "ELMER SOLVER FINISHED AT" in the output.
- Click on Close in the task panel after the run is finished.
- Two new result objects should be created in the tree view, SolverElmerResult and SolverElmerOutput.
