Reading coupling files

Jedi Knight Posts: 114 Join Date: 3/23/11 Recent Posts
Hi,

Is there a limit for the size of coupling files that can be read by Delwaq?

I have a water quality simulation of 1 month, with FLOW velocities etc taken from a 3D FLOW model of roughly 200*300 and 5 sigma layers. COM output is every 20 minutes.

I don't have an issue with reading in the COM file using .hyd, but when I try and read in the bed shear stresses output from the flow model, I get a 'grids do not fit' error message.

If I produce coupling files for just two weeks from the same FLOW model and COM file, I don't have an issue.

Are there any work around for this?

Thanks,

Ben

Hi Ben,

This looks like an old problem with WAQ-GUI thath cannot handle binary files bigger then 2 Gb. This is solved in recent version but I do not know which one you use. A work around is to import the smaller file in the GUI and after saving change in the <runid>.inp file the filename for the *.tau file to the big file.

The computational core of delwaq can handle files of any size.

Hi Jan,

That was very useful advice. Yes, I am using an older version of the Delwaq GUI.

I shall try to modify in the .inp file directly, as suggested.

Thanks,

Ben
