2D Taylor-Green-Vortex

[MarcoArtiano]

Hello,

I would like to run a 2D Taylor-Green-Vortex for a spatial and temporal accuracy analysis, but when I set up the same conditions as in input_2d.i3d, I get the following error:

''

TGV 2D: F

In auto-tuning mode......
factors: 1 2 3 6
p_row x p_col 2 3
2DECOMP&FFT ERROR - errorcode: 6
ERROR MESSAGE: Invalid 2D processor grid. Make sure that min(nx,ny) >= p_row and min(ny,nz) >= p_col

''
how can I fix this?

Thank you in advance!

Hi,
So I just tried to run the 2D TGV case using https://github.com/xcompact3d/Incompact3d/blob/master/examples/Taylor-Green-Vortex/input_2D.i3d and it is working fine with 6 and 8 MPI processes (with GNU Fortran 9.4).
Did you make changes to the input file?
Best,
Sylvain

Thanks, I made few changes, and after restoring it to the original version it is working again.
