Axisymmetric mesh generation in Pointwise like hollow cylinder geometry

Hi guys,
I am trying to create a mesh in pointwise for openfoam. I have hollow cylinder like geometry, so my axis of rotation is not on mesh surface, my inner face must be wall and not axis. I generate 2D axisymmetric (I hope) structured mesh (choosing 3D option and extruding around x axis by 5 deg and 1 cell long). Then I have three questions; 1) which axis must be rotation axis? is there a restriction in openfoam? 2) if there is no restriction, how can i tell to OF my rotation axis? is there a specific input file and option to define it? 3) Suppose I give the face boundary conditions correctly, but i couldn't figure out volume conditions in Pointwise. which volume condition do i have to choose in pointwise (ie. volumetocell, volumetoface etc. there are bunch of options)? |

There is no requirement to use a specific axis as your axis of rotation. It can be any of the three principal axes. If you create an axi-symmetric mesh, it needs to straddle a principal plane, see the image attached. Furthermore, you need to create two distinct wedge-type patches, since each wedge-type patch needs to be planar. |
