Re: [deal.II] Exception handling for multithreaded case

1.  Thus this issue would not exist for simple parallel tasks involving a reduction operation, such as computing average stresses over the domain, using Threads::new_task? Correct. This is the test that checks this:

David, It depends where the build files are written. Do you see the build files on your computer or do they exist only in the Docker container, i.e, after you've killed Docker do the files still exist somewhere on your computer ? Best, Bruno Le mar. 17 août 2021 à 09:00, David Montiel Taboada

Hello, I am working with step-29 and I would like to compute the solution for different frequency values (omega). For now, I am implementing a loop that updates *omega*, do the assemble and solve it. However, the simulations are slow due to the assembling in every loop iteration. Is there any

David, Have you try to create a new file and save it inside docker? What is your user name in docker? Are you root? It could be a problem with your permission. Best, Bruno On Saturday, August 7, 2021 at 3:07:56 PM UTC-4 dmon...@umich.edu wrote: > Sorry in my original email I wrote "This
