[Opm] Error with upscale_relpermvisc

[Alun Griffiths]

Hi

I have created a .grdecl file which was successfully upscaled using upscale_perm.  However, when I use the same file in upscale_relpermvisc, I get the following error message:

Error: Did not find SPECGRID, COORD and ZCORN in ECLIPSE file facies_2a.grdecl

I checked the .grdecl file and it contains these keywords so not sure what the issue is.

Best regards

Alun Griffiths
