### 2.7.6. Mesh Motion

All options for Mesh Motion are available for wall boundaries in domains where Mesh Deformation has been set to `Regions of Motion Specified`. For details, see Mesh Deformation.

Note: Unlike all other boundary condition values in ANSYS CFX, which are set on mesh faces, Mesh Motion boundary values are applied to all nodes on the boundary region. Care is therefore required to ensure that consistent Mesh Motion boundary conditions are applied at nodes that are common to adjacent boundary regions. For example, a `Specified Displacement` condition on one boundary region must produce no displacement for nodes that are common to adjacent boundary regions where `Stationary` conditions have been applied.
