Class
|
||||
Foam::uniformInterpolatedDisplacementPointPatchVectorField
|
||||
|
||||
Description
|
||||
Interpolates pre-specified motion.
|
||||
|
||||
Motion specified as pointVectorFields. E.g.
|
||||
|
||||
walls
|
||||
{
|
||||
type uniformInterpolatedDisplacement;
|
||||
value uniform (0 0 0);
|
||||
fieldName wantedDisplacement;
|
||||
interpolationScheme linear;
|
||||
}
|
||||
|
||||
This will scan the case for 'wantedDisplacement' pointVectorFields
|
||||
and interpolate those in time (using 'linear' interpolation) to
|
||||
obtain the current displacement.
|
||||
The advantage of specifying displacement in this way is that it
|
||||
automatically works through decomposePar.
