4. Continue selecting NEXT to proceed with defaults for the remaining pages. Enter text in the “Case Name” field at lower left and click Submit to start the simulation.

1.1.3. Review Results

From the Case tab select the case link under the Name heading to review simulation results. The following tabs present real-time data from the simulation.

1. Description: case submission details

2. Convergence: plots of nonlinear residuals, CFL ramping, and linear residuals

3. MinMax: plots and tables of flow field variable extrema, for debugging

4. Forces: plots and tables of integrated loads, totals and individual surfaces

5. Visualization: interactive mesh, contours, and isosurface display
