Dear all, I am new to PyFR. After I ran the example case-2D Euler vortex, the .vtu files were exported by 'pyfr export euler_vortex_2d.pyfrm euler_vortex_2d-100.0.pyfrs euler_vortex_2d-100.0.vtu -d 4'. I opened these .vtu files by Paraview 5.2.0, however, the streamline filter in Paraview is not ...

Hello, I'm looking to run a 3D simulation using PyFR and I'm having some trouble importing the mesh from Gmsh. I created the 3D mesh by extruding a 2D geometry that I have run successfully before. When importing the 3D mesh with PyFR I get the following error: ValueError: Unpaired faces in mesh ...
