Matthew Lenahan Posted January 19, 2012 Share Posted January 19, 2012 I have generated a flow model in PMWin and when importing the discretization file into X2t I get the following error: "non-uniform rows and columns not supported". My cell dimensions are 100x1x10. The top and bottom of the domain varies, but dZ remains constant. Here is the .dis file. Any advice out there? # Discretization file for MODFLOW-2000, generated by PMWIN 1 354 1 1 4 2 0 CONSTANT 100 DELR CONSTANT 1 DELC 105 1(1G14.0) -1 5.

Brian Farrell Posted January 30, 2012 Share Posted January 30, 2012 Hi Matthew, I moved your post to the main GWB page (it was in the archive for old posts, so I didn't see it right away). Could you please attach your budget file, and whatever X2t file you are using as well? I'll try to see if I can figure out what is wrong. One thing that immediately comes to mind (as being different from the GWB examples) is the lines which denote the top and bottom of the system (i.e. 105 1(1G14.0) -1 5. TOP OF SYSTEM). I'm not sure what those numbers and letters refer to, though I have not used the MODFLOW feature extensively.

Matthew Lenahan Posted February 1, 2012 Author Share Posted February 1, 2012 Those numbers instruct MODFLOW how to read the array we are using. All of the MODFLOW examples provided with GWB have constant TOP and BOTM of system (as well as nodal block geometry). Our flow model has varying top and bottom (BOTM), which is reflected in the .dis file that I pasted into the original post. We have edited our discretization file so that our model domain has a constant x,y,z (below). GWB is now happy to import the results from MODFLOW. # Discretization file for MODFLOW-2000, generated by PMWIN 1 354 1 1 4 2 0 CONSTANT 100 DELR CONSTANT 1 DELC CONSTANT 17.54 TOP of system CONSTANT 3.95 Layer BOTM layer 1 1 1 1 SS It seems that GWB can't import a flow model from MODFLOW if the geometry of that domain varies. Is this true??? Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted February 1, 2012 Share Posted February 1, 2012 Hi Matthew, Glad you got it working. I think you are right, currently GWB expects to find nodal blocks of fixed dimensions (and elevation) when importing flow fields from MODFLOW. Cheers, Brian Quote Link to comment Share on other sites More sharing options...
