CFD-VIEW Colormap Options: Static, Dynamic, and Cumulative
The Colormap Settings panel in CFD-VIEW assigns colors to data sets. Identical data values on an object are displayed with the same color if they are using the same colormap display. Three options offer the user the opportunity to select the mode for updating the...

Boundary layer meshing with CFD-ACE+  [video format]
The accuracy of a CFD solution is strongly dependent on how well the mesh resolves geometry and flow features. This is especially true for near wall regions (boundary layer) where viscous forces are not negligible compared to inertial forces.
