setSet is a utility that collects points, faces and cells in sets, based on different criteria, for later usage with different other utilities like subSetMesh.
Following is an example of the usage to fix an imported mesh that has small faults.
Running checkMesh on this geometry:
foamJob -s checkMesh -allTopology -allGeometry
generates some warnings and errors, but most important, several sets: cellZone_1, cellZone_2, concaveFaces, edgeFaces, nearPoints, nonOrthoFaces, skewFaces, undedeterminedCells, warpedFaces, wrongOrientedFaces. The next step is to collect all the cells that contain any of the concave faces, incorrect edge faces, warped faces, wrong oriented faces, or cells with a very small determinant:
setSet -constant Command>list Command>cellSet bubu new cellToCell underdeterminedCells any Command>list Command>cellSet bubu add faceToCell concaveFaces any Command>cellSet bubu add faceToCell edgeFaces any Command>cellSet bubu add faceToCell warpedFaces any Command>cellSet bubu add faceToCell wrongOrientedFaces any Command>cellSet bubu invert Command>cellSet bubu subset Command>quit foamJob -s subsetMesh bubu
