Error partitioning the mesh

Just Starting
1

I am trying to partition the 2D Euler vortex test case with Metis 5.2.1, by
pyfr partition add -p metis euler-vortex.pyfrm 2 .
I get the error: ValueError: Invalid partitioning name
Has the command for partitioning changed from that given in the documentation? I tried to follow pyfr partition add -p metis mesh np name.

I think you can just drop the . at the end.

That helps with 3 of the 2d examples - double mach reflection, shock tube and cylinder. For the other cases, 3d & 2d, a segmentation fault is thrown.

Do you have the exact command you are using along with the precise version of PyFR?

PyFR 2.1, compiled from source using setup.py.
pyfr partition add -p metis euler-vortex.pyfrm 2

Edit:
Using scotch gives the same error for these cases.
pyfr partition add -p scotch -e quad:3 -e tri:2 couette-flow.pyfrm 2

That is not the correct syntax for v2.1. The “add” syntax is new in the development version of PyFR v3 which uses a different file format.

Please use v2.1 from PyPI.
