Detailed Description

template<class Type>
class Foam::timeVaryingMappedFvPatchField< Type >

Patch field mapper which interpolates the values from a set of supplied points in space and time.

By default the data files should be provide in constant/boundaryData/<patch name>/ directory:

  • points : pointField of locations
  • <time>/<field> : field of values at time <time>

Alternatively the names and locations of the points and field files may be specified explicitly via the optional dictionary entries:

  • dataDir <optional top-level directory of the points and field data>;
  • points <optional path including name of points file relative to dataDir>;
  • sample <optional name of the sub-directory in the time directories containing the fields>; This is particularly useful when mapping data from another case for which the sample functionObject is used to obtain the patch field data for mapping.

The default mode of operation (mapMethod planarInterpolation) 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

mapMethod Type of mapping no planarInterpolation
offset Offset to mapped values no Zero
dataDir Top-level directory of the points and field data no constant/boundaryData/<patch name>
points Path including name of points file relative to dataDir no points
sample Name of the sub-directory in the time directories containing the fields no ""
