Thank you for your reply Prof. Bangerth. I believe I am already using distributed computing in my code. But I am not sure it is true for the post processing part. I use write_vtu and write_pvtu_record to write the output files. Is that the best way to do it in distributed computing? Is there any example where distributed computing is implemented in the post processing so that I can compare my code and see if it can be improved?
Thanks in advance, Raghunandan. On Tuesday, August 23, 2022 at 12:06:37 PM UTC-5 Wolfgang Bangerth wrote: > On 8/23/22 07:22, Raghunandan Pratoori wrote: > > > > I have 2 sets of dof_handlers.
