splitMesh
|
|
|
|
Description
|
|
Splits mesh by making internal faces external. Uses attachDetach.
|
|
|
|
Generates a meshModifier of the form:
|
|
|
|
Splitter
|
|
{
|
|
type attachDetach;
|
|
faceZoneName membraneFaces;
|
|
masterPatchName masterPatch;
|
|
slavePatchName slavePatch;
|
|
triggerTimes runTime.value();
|
|
}
|
|
|
|
so will detach at the current time and split all faces in membraneFaces
|
|
into masterPatch and slavePatch (which have to be present but of 0 size)
