I'm really sorry for the lack of professionally here, but I was really lost. Even by using the JetBrains' CLion debugger, with the newly learned trick of file-based trigger and attaching the debugger to one of the processes, I hadn't got an answer.
But now I *solved it*. The fix consists in calling just before this->triangulation->prepare_coarsening_and_refinement(); After that it works smoothly. I hadn't seen this in tutorials like step-40, I though prepare_coarsening_and_refinement() was meant to be used only before doing SolutionTransfer, should it always be called in parallel triangulations? Thanks a lot if anybody wants to clear to me this theoretical doubt, otherwise case closed :) Best, Matteo Il giorno lunedì 3 febbraio 2025 alle 18:25:50 UTC+1 Wolfgang Bangerth ha scritto: > On 2/3/25 10:15, Matteo Malvestiti wrote: > > But here it breaks... sometimes. > > > > Let me explain my bewilderment: > > It may go well for 6 refinement cycles and break at the 7th. > > > > Does anybody have any hint at what I should investigate to figure out > the problem? > > A good starting point is to clearly articulate what happens.
