Description🔗
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.
Usage🔗
The condition requires entries in both the boundary and field files.
Boundary file🔗
<patchName>
{
type patch;

Field file🔗
<patchName>
{
// Mandatory entries
type timeVaryingMappedFixedValue;
