2 Attachment(s)
hi
I solved flow between two cylinders by COMSOL and now I'll do it by OF (I am beginner). I want to use makeaxialmesh utility and Gambit but I dont know define
-axis for makeaxialmesh (red line in pictures)!!
do I need to do something on gambit model ?
please guide me
Regards

Have a look at the axialCavity-Testcase that is in the SVN-repository. It defines exactly such a case (using the rotationDict)

Just one remark: you might prefer creating a quad-mesh instead of the triangles (and BTW: gambit is a bit of an overkill for that geometry)
