Class
    Foam::fvMeshTopoChangers::meshToMesh
 
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;
    }
