The timeVaryingMappedFixedValue is a boundary condition that interpolates the values from a set of supplied points in space and time.

Supplied data should be specified in constant/boundaryData/\<patchname\>/ - points : pointField of locations - \<time\>/\<field\> : field of values at time \<time\>

The default mode of operation (mapMethod = planar) is to project the points onto a plane (constructed from the first three points) and construct a 2D triangulation and finds for the face centres the triangle it is in and the weights to the 3 vertices.

The optional mapMethod nearest will avoid all projection and triangulation and just use the value at the nearest vertex.

Values are interpolated linearly between times.


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

Boundary file

    type            patch;

Field file

    // Mandatory entries
    type            timeVaryingMappedFixedValue;
    uniformValue    <PatchFunction1Types::MappedFile<Type>>;

    // Inherited entries


Property Description Type Required Default
type Type name: timeVaryingMappedFixedValue word yes -
uniformValue Data PatchFunction1Types::MappedFile<Type> yes -
