I am trying to set up groundwater flow model over the Ganga Basin (0.4 million sq km) using Modflow. I am using Visual Modflow Classic and Modflow 2005 engine. I had set up the transient model but I am facing some difficulties. Therefore I am attempting to set up steady state simulation using lone term average values of pumping at each of the 3800 locations of pumping wells and similarly long term average for recharge, lateral inflow, boundary conditions. However, the model shows an error as soon as I click the run button (after model translation). I have attached the.LST file. The error in the file refers to row 1 and column 500 but the corresponding grid is an inactive cell in the model. Can you please help me decode the error and rectify it?
you have a very large area and a thousand of data; that need the high capability of a laptop and professional software. it's very hard to run your simulation with Visual Modflow 2005 ;
there is best free modeling to integrate with GIS QGIS is FREEWAT using the MODFLOW code

Hi Ishita,
The model area is quite large but I think you can make a flow model with Visual Modflow. Is it a single layer model?
It seems that the model layer's top and bottom are highly variable (i.e., steep slopes). You are using the WHS solver; try to use different solvers and see if any other works.
Thank you Sir! The problem got resolved. There was one cell marked as active in the inactive zone. Yes it is a single-layered model. The slopes are steep but only at the edges of the model active domain.
