Answer:
After a successful calculation, the checksums of drag forces are displayed on the original model and on the simplified model in RWIND Simulation in the legend of the graphic window. They represent the resultants of the wind load in the global directions X, Y, and Z.
You can use it to compare the drag forces acting on the original model and the simplified model.
The simplified mesh is a special mesh that envelops the original model, and thus defines the model boundary.
If there are significant differences between the checksums, you should increase the level of detail in the Edit Model dialog box for a more refined, simplified model.
However, if there are any differences, please note that any closed openings may also have an influence on the checksums.
