Hi everyone,

When I try to link the MODFLOW NWT files to WEAP, I get the following error:

Error reading MODFLOW Discretization file

Bad format--not a valid integer:" "

File: %%.dis
Line: 4
Position: 51
Contents: 0 50.00000 (10E20.12) 0

So basically there's a problem when reading the .dis file (so far). What is the problem with the format? I actually looked at the .dis format in the MODFLOW guidelines for input files and there seems to be nothing wrong.

Any ideas?

Kind regards,
Esteban

Hi Esteban,

I've been through the same issue when using fixed format and fixed it by erasing the space between the real number (50.0000 in your case) and the format ( (10E12.4) in your case ). The same will happen with 1D or 2D arrays when you set IPRN = -1. I would suggest using free format to manually edit the packages.

It seems to be an issue on how WEAP read and rewrite the packages.
