### 5.1.6. Mesh Displacement vs. Total Mesh Displacement

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.
