I have problems running PEST NSMC with fixed pilot points. Both in my own model and in the NSMC tutorial files, I get the same error message "Cannot open parameter value file nsmcII_200_random_nul.par." and the simulation finishes without completing any iteration. Is this a bug i in GMS? Kind regards, Jonas
Hi, When i customize the variogram for the pilot points of the HK-field in the nsmc I and II tutorials, and also in my own models, I encounter the problem showed in the attached figure. It seems like the whole field is generated from only one point and not all available ones. I also edited the already set up variogram in the tutorials, and then changed back to its original form and still got the same problem. Any ideas on how to solve this issue? Kind regards, Jonas
Jonas posted a topic in Using GMSHi! I have set up a model for a municipal water supply in an glacifluvial esker. I want to calibrate the hydraulic conductivity (HK) against steady-state heads in the esker material with PEST and pilot points. I also have other materials in the model but with a fixed HK. The recharge is also calibrated with PEST in three different polygons. The picture below shows layer four (of five). Left shows materials (only bedrock and esker in this layer) together with locations of the pilot points. The middle part shows calibrated heads after PEST has been running. Right shows HK after calibration with PEST. My issue is that the area with esker material (left) does not overlap the area that is calibrated with pilot points in the rightmost picture (non red area). Something that looks strange in particular is the straight paths from the middle to the south of the model that get the same HK as the bedrock although the material is set to esker. It is the same issue in the other layers of the model. Ideas on how to solve this issue are appreciated. Kind regards, Jonas
I am running a model and refined it using the pilot points and am using the HUF package rather than the LPF package as suggested in the tutorial. I am trying to import the optimum values back to the model and do not see a way to attach them to the associated material. I have tried running the model after importing the optimal values and I again get my initial huge errors as the pilot points were never imported. If you have any advice on how to import these values it would be much appreciated. Version is 10.0.11 Greg
