  1. Hello. I am having the same problem, but I am unable to run MODPATH even when I manually click "run modpath". My model is the classic Henry problem and includes the SEAWAT module. Every time I try running the model I get the following message: "Pathlines not computed because no MODFLOW cell-by-cell flow solution file could be found. Turn on on the cell-by-cell file output option in MODFLOW Output COntrol, or turn off Pathlines in the Project Explorer to avoid this message." I have tried turning everything on in MODFLOW Output Control, and it still doesn't work. Is there a way of making this work? Alternately, is there a way of using the final flow solution from SEAWAT as a steady state solution on MODFLOW and simply running MODPATH within this solution? Any help is much appreciated
  2. I have had the same problem. I found out that the problem was that I had used negative values for certain model parameters, including horizontal K so I could specify them under MODFLOW -> Parameters, for inverse calibration. The solution was to enter all the parameter values manually after the calibration was done Lau
  3. Hi. I am trying to create a simple saltwater intrusion model (The Henry Problem) where I include direct age modelling. For this I need two species: "Salt" and "Age". At the western side of the model I have a constant head boundary with constant salt concentration. In the eastern side I have a constant flow boundary with constant concentrations for both Salt and Age. The problem is that I haven't found a way to implement the constant salt concentrations at the western side without having to specify a constant age as well. Has anyone found a way to specify the concentration of only one out of several species? Your help is appreciated Lau Petersen
  4. Fixed it. If anyone else encounter this problem, the solution is to run GMS as admin
  5. I have encountered a problem on several different computers at my institute. It seems that everything displayed in the display window stays there - so when you zoom out or in, for example, the old picture will stay in the window as well as the new one - screenshot added for clarification. The problem occurred in GMS 9.2 64-bit. It only occurs on some computers. Has anyone encountered this problem, and does anyone know of a solution?
