undoableMeshCutter Class Reference

The main refinement handler. Gets cellCuts which is structure that describes which cells are to be cut and in what way. Maintains an undo list (if told so during construction). Apart from undo list is just wrapper around meshCutter. More...

Detailed Description

The main refinement handler. Gets cellCuts which is structure that describes which cells are to be cut and in what way. Maintains an undo list (if told so during construction). Apart from undo list is just wrapper around meshCutter.

Undo list: contains a refinement tree (of type splitCell; cell labels are of no consequence) and a list of visible splitCells, i.e. the top of the tree (where the cell labels are valid). Now every cell added gets put on the tree and every updateMesh action updates the labels of visible splitcells.

We can now ask this structure for a list of visible split cells or the list of faces between these. These can be passed to removeFaces for actual deletion and we delete the top splitCell and update the now newly visible underlying cells for the new cell number (passed back from removeFaces).

NOTE: Undoing note properly tested. Expect it to fail if the faces to be removed cause other faces to be additionally removed (i.e. removeFaces adds additional faces to remove).
