Please see the added tests.

working on the pipe system but failed to get it work. Any thoughts?

dynaryu commented 12 months ago

Please check test_sys_fun_pipes1 in test_pipes_sys.py. I compared the results before and after changing to zero-based index, and noticed that the resulting sys_val is different from -1.0 (which I assume a true value). Any thoughts?

jieunbyun commented 12 months ago

When I see test_sys_fun_pipes1, the input component state is {'n1':0, 'n2':0, 'n3':0, ...}, and I get as sys_val -0.0. The result is correct since zero flow will happen with all those nodes connected to the origin nodes having zero capacity.

I thought that sys_val should be the same even after the code was changed to zero-based index. Otherwise some part of the code was not changned properly. Any thoughts?

What's the expected output given the all of the comp states are 1 before the code was changed? When I ran the code, the output was -0.1.

I re-run the code, and strangely I got 0 for this time. I am a bit confused. Anyway, I'll look into the issue.
