<DIV dir=ltr>hello, <BR> <BR>I try to generate a mesh for use in OpenFoam by gmshToFoam conversion, but I alwas get the warning:</DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>--> FOAM Warning :<BR> From function polyMesh::polyMesh(... construct from shapes...)<BR> in file meshes/polyMesh/polyMeshFromShapeMesh.C at line 576<BR> Found 28864 undefined faces in mesh; adding to default patch.<BR>Finding faces of patch 0<BR>Finding faces of patch 1<BR>Finding faces of patch 2<BR>--> FOAM Warning : Not using gmsh face 4(1446 14016 14017 1447) since zero vertex is not on boundary of polyMesh<BR>.........</DIV>
<DIV dir=ltr> <BR>However i got polymesh directory with all files. but the faces or boundaries are not reading. <BR>patches in boundary files are even taking nFace=0 even if startface#0 in some patches. </DIV>
<DIV dir=ltr>it seems to be arbitrary because i change many times the order and the way to define the physical surface and the result is different all the time.<BR></DIV>
<DIV dir=ltr>here attached my script. and checkMesh outline. </DIV>
