You can use results at a fluid-structure interface from a CFD analysis as face forces (from the vector sum of the normal pressures and shear stresses) on corresponding faces in the Mechanical application. The import process involves interpolating a CFD solution onto the Mechanical application face mesh. This requires that the following conditions are met:
The fluid-structure interface must be a defined boundary in CFD.
The location of the CFD boundary (with respect to the global Cartesian coordinate system) must be the same as the corresponding face(s) in the Mechanical application model.
Refer to the Imported Boundary Conditions section for more information.
