Hello Everyone,
I am trying to run a simulation of the T106A Low-Pressure Turbine blade with PyFR version 1.12.2.
I found the geometry model of the T106A Low-Pressure Turbine blade at http://www-g.eng.cam.ac.uk/whittle/T106/Start.html as one .iges file and I am trying to produce a mesh for that model with the Pointwise software. In particular, this software allows exporting the CAE model of the grid both in GMSH and PyFR formats.
Apart from more advanced issues (like the resolution that I am using now, which is very coarse), I am not able to make PyFR accept the mesh.
I report in the following the errors given by the two formats that I tried:
.msh Error

I am new to this kind of meshing, therefore any hint from the community is more than appreciated.
Moreover, I cannot find a way to attach the mesh files that I produced, but if anyone may tell me how to do that, I can share those files.
