Default Immersed Boundary Mesh Problem

I did cylinderInChannelIcoIbFoam and movingCylinderInChannelIco tutorials succesfully. ( and

I want to define new cylinders instead of tutorials' cylinders. I created it in ANSYS DesignModeller and made it as surface body, then meshed. At this point I have cylinder.msh

Now I want to change this .msh file to .stl in order to use it in immersed boundary tutorials. I typed fluentMeshToFoam cylinder.msh. I get fatal error.
cannot find a single face in the mesh which uses vertices 3(1 0 2)
From function findFace(const primitiveMesh&, const face&) in file fluentMeshToFoam.L at line 856.

Then I typed fluent3DMeshToFoam cylinder.msh. It worked.

After this I tried this method to create cylinder.stl :

This creates a dummy file that identifies the grouping of files as proSTAR files.
  • surfaceMeshConvert surfExport.inp surfExport.stl
Convert to STL (or other) surface format.
At the end I open my geometry with paraView but I see nothing. So embarrassing.

Any idea?

If all you need is a cylinder, make it in Paraview, triangulate the geometry (filter) and save data to STL. Apart from that Ansys DM cannot export STL? Really surprises me.

Even if Ansys Design Modeler could export STL, I wouldn't need it. I need a mesh file because I want to set the delS (I mean delta S in immersed boundary and it has to be equal to delta X in blockmesh) and to convert it STL.
