Description

The translatingWallVelocity is a velocity boundary condition for translational motion on walls that sets the velocity parallel to the wall to a given value, e.g. to approximate a moving ground plane. The patch normal velocity component is set to zero.

Usage

The condition requires entries in both the boundary and field files.

Boundary file 

<patchName>
{
    type            patch;
    ...
}

Field file 

<patchName>
{
    // Mandatory entries
    type            translatingWallVelocity;
    U               <Function1<vector>>;

    // Inherited entries
    ...
}

where:

Property Description Type Required Default
type Type name: translatingWallVelocity word yes -
U Translational velocity Function1<vector> yes -
