I generated mesh with Pointwise, and tried mesh partition but I got an error.

pyfr partition 8 lrn1015_structured_2c.pyfrm .
Traceback (most recent call last):

I succeed performing mesh partition with tutorial cases, so I gueesed this problem is unique for mesh generation process with Pointwise. Is there any solution for this issue?

Pointwise have not updated their PyFR export support in many years. I also do not believe that it ever supported high order (curved) grids; as such it is worthless.

Export to Gmsh and import into PyFR.
