Dear foamers ,

I am simulating an engine with sonicTurbDyMEngineFoam and simpleEngineTopoFVmesh library....

In a 2D case that mesh generated by using blockMesh there are two boundaries (valveDetachCyl &valveDetachPort) that they dont have any faces in blockMeshDict file....This will lead to creat this boundaries in the boundary file in the polymesh directory...
My problem comes when I generate the mesh by using Gambit... when I use fluentMeshToFoam this will lead to creat boundary file and I cant add a new boundary face manually in the boundary file because I dont know startFace...

please anyone help me? existing of these boundaries in the boundary file (polymesh/boundary) is necessary?
