All, I am doing this in code using vtk, but can be reproduced using paraview as noted below.
I have a 2d mesh which represent a cylindrically symmetric simulation. I want to be able to revolve this around the z-axis to create a 3d mesh. However, when doing this using the rotational extrusion filter, I only seem to have boundary faces. I can't get this to give me 3d cells inside the volume of revolution, which is what I'm after. Can this be done? I have done this in visit and sure enough the mesh is inside the volume of revolution as I expect. This can be reproduced in paraview using the UCD_00003.inp example from the data set. First apply a transform and rotate around 90 degrees round the y axis. Then apply the extract surface filter. I too must do this in my code as the incoming mesh is a vtkUnstructuredGrid and the rotational extrusion filter wants a polydata. Then apply the rotational extrusion filter for 360 degrees with 120 resolution. Finally perform an x-normal slice at the default position. Viewing only the slice shows the outer boundary only, but I had wanted the interior of the boundary to be populated with a mesh, not bothered about its topology, just want a fully populated mesh within the interior. Again, any help on the above really appreciated?? As I say achieved with visit....which I mention only because I assume the code under the hood would be vtk and hence possible in my case. Many thanks, Andy
