Error when writing output files.

Post by waterislife » Tue Sep 20, 2022 12:50 pm

Hello,
I get the below error when running monte carlo simulations using matlab. 302 of the 1000 simulations executed properly then at iteration 303 I got the below code. Why would hydrus all of a sudden have trouble writing to an output file? There was no indication that the iteration didn't converge. Also two files were generated in the same location of the .exe with these errors. fort.71 and fort.77. They are both .txt files with the content of "end"

You should try to rerun (individually) the run that failed to see what’s going on. This usually occurs when the code does not converge (in either the flow or solute part). J.
