Cannot get ModelMate (UCODE) to function with my model!

[Coleman Hiett]

Hello everyone,

I am working on a "simple" MODFLOW model that I created using ModelMuse, and after getting it to run to completion I am now attempting to import the parameters and observations into ModelMate to calibrate the model and hopefully optimize the parameters. My model involves a small unconfined alluvial delta with a single stream and a pumping well. I have defined what I can with parameters and have four observation wells, each with two head observations (4 head observations in stress period 1, 4 head observations in stress period 2). This is a steady state model with two stress periods (the first without pumping and the second with pumping). I am able to get this model to run to completion in ModelMuse, but when I try to calibrate it with ModelMate (UCODE) I run into this problem: 

-- UCODE cannot read my model output files(?). I am using the "ModelMate_tutorial.pdf" file that comes with the ModelMate directory as a template. After successfully getting the  “tc1” MODFLOW-2005 (Harbaugh, 2005) model to work with ModelMate, I am using the same steps with my model to no avail. After importing all of the parameters and observations, assigning a model command line, and creating the UCODE Input files, I attempt to run UCODE on forward mode. In the windows command window, the program appears to evoke MODFLOW and solves my two stress periods. A line below says "Normal termination of simulation" but then another line directly below says "Error reading model output file(s): cannot open model output file   ...hob_out.".   When I view the UCODE Main Output File (...main_out.#uout) it displays my observations and parameters as it should but after the line that says "END ECHO OF INPUT - REPORT RESULTS OF SIMULATION" I get a line that reads [Error in instruction: " " ]. My Model-Output File and Instruction file are listed in within ModelMate, although I cannot find the instruction file saved anywhere (I can find and read the "... .hob_out" file but there is no "... .hob_out.jif" file saved anywhere except listed under the Model-Output and Instruction Files window in ModelMate). I have read all of the ModelMate instruction file, and using the Model|Create Instruction Files For Observations Defined In ModelMuse function does not solve my problem. 

I have tried everything I can think of. There are no spaces in the file names or anything like that. Any ideas or similar issues?!?

Thanks for the help!

Hi, I am coming across the same problem, and have no idea how to get around it. Did you manage to solve your issue?

Thanks in advance!
