Description
fvMeshTopoChanger which maps the fields to a new mesh or sequence of meshes
which can optionally be mapped to repeatedly for example in multi-cycle
engine cases or cycled through for symmetric forward and reverse motion.
Usage
\table
Property | Description | Required | Default value
libs | Libraries to load | no |
times | List of times for the meshes | yes |
repeat | Repetition period | no |
cycle | Cycle period | no |
begin | Begin time for the meshes | no | Time::beginTime()
timeDelta | Time tolerance used for time -> index | yes |
\endtable
Examples of the mesh-to-mesh mapping for the multi-cycle
tutorials/incompressibleFluid/movingCone case:
\verbatim
topoChanger
{
type meshToMesh;
libs ("libmeshToMeshTopoChanger.so");
times (0.0015 0.003);
cycle #calc "1.0/300.0";
begin 0;
timeDelta 1e-6;
}
