Also, if you want to preserve the connectivity of the original mesh and save some time, there’s a VTK filter called vtkVolumeOfRevolutionFilter which can rotate 2d polygonal data around an arbitrary axis to create 3d volumetric output. There isn’t a Paraview interface for it, so I wrote a small XML-only plugin for it:
VolumeOfRevolution.xml (1.9 KB)
Since the filter is already in VTK, this XML file can be loaded using the plugin manager to allow rotation of 2d axisymmetric data into a 3D volume mesh with variable resolution around an arbitrary axis; it’s almost an identical interface to the Rotational Extrusion filter, but actually makes volumes. Hope this helps!!
