Issues in Running the OpenMOC Code

[Iqrar Hussain]

Hello, Good Morning dear Developer of the code!

I have installed the OpenMOC, but by running the test problems already available in the "tests" folder inside OpenMOC file, I am getting the error "python3 test_1d_gradient/test_1d_gradient.py

Traceback (most recent call last):
  File "/home/iqrar/OpenMOC/tests/test_1d_gradient/test_1d_gradient.py", line 8, in <module>
    from testing_harness import TestHarness

ModuleNotFoundError: No module named 'testing_harness'", but, actually testing_harness.py file is available inside "tests" folder. Similarly, when this issue is resolved then it shows some other missing, but, actually which is also available inside "tests" folder. 

Therefore it is requested your honor to help me in this basic issue (as i am the beginner), so that i may be able to run the already available test problems and move forward further in my work. Thanks!

Regards,

Iqrar Hussain.

Hello

It could be that exporting the path to openmoc/Python or openmoc/OpenMOC to the PYTHONPATH is enough to fix these import issues. 

You can append to that environment variable using « export » on unix
