karam_j is on a distinguished road
Hello, i am running a simulation with UDFs that converged properly when using 4 cores/processes and the results are sensible.

Running the same case using the same settings with 0 changes on any other number of cores causes divergence within the first couple of iterations.

Does anyone have any idea what could be happening here? Thank you in advance.
