Euler 2d example partition issue

General

Hi ,

I’ve been trying to run the EULER 2D vortex example and I’m getting an error. I’ve followed the steps according to the user guide and when I’m typing this command
pyfr partition 2 euler_vortex_2d.pyfrm ., I am getting

Input Error: Incorrect numflag.
Traceback (most recent call last):
File "/gpfs/cfms/apps/pyFR/py34/bin/pyfr", line 9, in <module>

pyfr.partitioners.metis.METISErrorInput

Any ideas ? All the packages have been installed and sourced accordingly.

I would appreciate your help.

pyfr.partitioners.metis.METISErrorInput

It is possible that PyFR is giving METIS a bad graph to partition
(although this is a standard mesh). However, it is more likely to be
a problem either with METIS or how we interface with it. (There is
some complicated code within PyFR that attempts to determine the
options that METIS was compiled with.)

Given that the partitioning works on both of my systems do you have
any details with regards to how METIS was compiled?
