KNOWN ISSUE: Callbacks and Additional Variables which are functions of Mesh Displacement may give incorrect results (Class 3 Error)
An Additional Variable which depends on Mesh Displacement may have incorrect hybrid values, which can be seen when viewed in CFD-Post.
A callback function which is evaluated on boundary faces (e.g. areaInt) and depends upon Mesh Displacement will give incorrect results if the boundary faces are moving.
The CFX-Solver is calculating the Mesh Displacement on faces incorrectly. The nodal values are correct.
No workaround is currently available.
