Dear Wolfgang,
Thank you very much for your answer. Regarding what you mentioned:

*file and writing to it. Nothing good will come of this. There is of

Hello team,
I am trying to run a simulation with grid refine factor 7. I know this is
significantly large and any improper code will raise memory issues. I am in
fact getting memory issues after completion of first time step and I am not

parallel::distributed::Triangulation is just not implemented for dim==1 so
you can't run step-40 for the one-dimensional case.

Dear all,
I was trying to run step-40 in 1 dimension and encountered the

Dear all,
after some time I came back to this problem again. I would kindly ask for
some guidance to see if I can understand and solve the issue.
I am using a parallel::distributed::Triangulation with MPI. I call the
