Cannot run Fenics code with fine mesh (memory issue?)

[dokken]

Well, now you are getting another error, not out of memory.

@mekong

*** Reason: Solution failed to converge in 0 iterations (PETSc reason DIVERGED_PC_FAILED, residual norm ||r|| = 0.000000e+00).

You can again search for this error on the forum ,getting results like:

ArityMismatch error

Thanks for the insightful take. I appreciate it. Kindly provide your mesh file (in this case .xml file) with a minimum working example so that I can reproduce the error and could possibly give any suggestion. According to @dokken in this post PETSc Krylov Solver RuntimeError with fine mesh , this information means that the residual is zero at the first iteration, which usually indicates that the initial guess solves your problem. This was also reported for another case at the old Q&A forum. …
