By convention, the numerical return code return code of successful program is 0 (search something like "program return code convention"). Non-zero values would mean some error during running. > I was able to assemble a complete file. > I leave it here for your reference. Thanks, but please make it working, especially without syntax errors, .e.g line below from yade.params.table import * sigmaIso = -200e3 #import matplotlib > However, my program outputs only the log file. > Can you please tell me what is wrong with the program? Obviously syntax errors are wrong. Otherwise (assuming this is some copy-paste newline problem), I don't know. I have run your simulation and it did export data files sucessfully (e.g. for my case 20230315T150806p19057.txt) What exactly is "the result file"?

However, my program outputs only the log file. I also wanted to create a batch file with a different radius, so I created a program, but it only created a log file. Can you please tell me what is wrong with the program? Also, What does status : 0 (OK) mean?
