Hi paraviewers, I am using paraview to render results in CFL3D, which is in Plot3D format, including `abc.xyz` grid file and `abc.q` solution file. Besides, I have a boundary condition file `abc.xyz.fvbnd` in FieldView 1.3 format which was generated by grid pre-processor.
My problem is: How to extract the surface of the aircraft? Because the Plot3D format is a multi-block curvilinear grid. When I use `Extract Surface` filter, it will extract the block interfaces. My current solution to combine blocks by `Merge Blocks` filter. Then I can extract the surfaces, including the outer boundary and the inner aircraft walls. After that, I need to clip the farfield and keep the aircraft walls. Is there a better solution? However, what I need to do is to evaluate the force on specific parts. So I need to use the information from the boundary condition file `abc.xyz.fvbnd` which indicates ranges of indexes in curvilinear grid as wall of certain parts. My problem is how to use it to generate several surfaces in paraview for rendering and integration. p.s. I am using paraview 5.4.1. The grid consists of farfield outer boundary and several aircraft parts' wall inner boundaries.
