Export native modflow files with Pilot Points

Recommended Posts

Hello,

I have encountered a problem with exporting native modflow files from GMS. Some of the model parameters are defined using Pilot points. Lets say that I would like to use different version of MODFLOW to calibrate the model. I have succesfully exported the MODFLOW native files and I was able to start USGS version of modflow. The input data are read correctly, first stress period is solved, however during the second period MODFLOW stops. Here is the end of the output file:

 

PERCENT DISCREPANCY =          -0.03     PERCENT DISCREPANCY =          -0.03






         TIME SUMMARY AT END OF TIME STEP    1 IN STRESS PERIOD    1
                    SECONDS     MINUTES      HOURS       DAYS        YEARS

         TOTAL TIME 2.67840E+06  44640.      744.00      31.000     8.48734E-02

                              NUMBER OF TIME STEPS =     1

                               MULTIPLIER FOR DELT =     1.000

                            INITIAL TIME STEP SIZE =   29.00000

 PARAMETER "GHB_3405  " IN PARAMETER INPUT FILE HAS NOT BEEN DEFINED

 PARAMETER "GHB_3409  " IN PARAMETER INPUT FILE HAS NOT BEEN DEFINED

 PARAMETER "GHB_3406  " IN PARAMETER INPUT FILE HAS NOT BEEN DEFINED
 -- STOP EXECUTION

When modflow starts no interpolation is performed for the pilot points. I assume there is some custom routine in the GMS version that handles the interpolation from PP to the MF grid array. Please advice how this is supposed to be handled or what am I doing wrong.
