A number of new variables become available when executing simulations with mesh deformation. Two of these variables are Mesh Displacement and Total Mesh Displacement.

Mesh Displacement is the principal variable that is solved for by the mesh motion model (see Mesh Deformation in the CFX-Solver Modeling Guide). This variable represents the displacement relative to the previous mesh locations. Conversely, Total Mesh Displacement is a derived quantity that represents the displacement relative to the initial mesh.
