Overview

The makeFaMesh utility creates finite-area meshes from volume-mesh patches.

Usage

Synopsis 

makeFaMesh [OPTIONS]

Examples

Run makeFaMesh and write the mesh as a VTK file for display:

makeFaMesh -write-vtk

Input

Files

The makeFaMesh utility is configured using a <case>/system/faMeshDefinition, taking the form:

polyMeshPatches             ( <patch1> <patch2> ... <patchN> );

boundary
{
    <faPatch1>
    {
        type                <word>;
        neighbourPolyPatch  <word>;
        ownerPolyPatch      <word>;
    }
}

defaultPatch
{
    name    <word>;
    type    <word>;
}
Property Description Type Required Default
