The "Constrained Displacement" Grid Deformation Feature

The "Constrained Displacement" Grid Deformation Feature
When running Fluid Structure Interaction (FSI) problems with CFD-ACE+ you may run into problems with severe grid skewness in the fluid regions. While the CFD-ACE+ Stress module solves for the deformation of the grid for the solid part, the CFD-ACE+ Grid Deformation... read more
