Where should I post computational physics "check my work" threads?

[Wrichik Basu]

I have written some programs for solving partial differential equations, and they are not working out as they should, i.e. the numerical solution is not matching the analytic value. I need some help in figuring out where the problem is occurring. These are essentially "check my work" type problems.

Where should I post such threads? In the intro physics homework help? Or advanced physics homework help? Or somewhere else? I prefer not to post in the Engineering and Comp Sci Homework forum as this is neither engineering, nor computer science; this is specifically computational physics. There seems to be no forum specifically for computational physics problems.

Since they are problems with differential equations why would you not just post them in the differential equations forum?

Because the problem is with the program (Python/MATLAB). That's why I was a bit hesitant to post it in the diff. eqns. forum.

Ah. Reasonable. Well, then, "Programming and Computer Science".

This has a Physics portion attached to it as well. In the programming forum, I haven't seen any computational physics question recently. I was thinking to post somewhere in the physics section...

"Check my work" is a really heavy ask.

You can make it easier with well-documented code, easy to understand variable names and logic structure, and the minimum example needed to demonstrate the problem.

You ended up posting this in "Other Physics" - that's not a good choice.

would have been better, but it really should be in homework and so "Engineering and Comp Sci Homework" is the right place.

I posted there because I found another unanswered thread on computational physics in that forum. It's quite high up in the unanswered threads panel in the RHS, but no Mentor has moved it yet. So, I thought that would be the correct place.

This is not Engineering. In addition, it also has some physics in it, not only computer science.

This is not Engineering.

The topic is for problems related to Engineering or problems related to Computer Science, not exclusively problems related to both Engineering and Computer Science.

In addition, it also has some physics in it, not only computer science.

Do not confuse the model with the application: exactly the same PDE has applications in biology, chemistry, engineering, economics, financial mathematics...
