All: We thought it would be a nice idea to introduce a deal.II-based Paper of the Year Award that we could hand out every year -- nothing that comes with a big money prize or important international festivities, but something that recognizes the authors of papers that use deal.II in particul

I figured out the problem. In my make_constraints() function, I re-initialized the AffineConstraints object indeed with the locally releveant DoFs as you said (although this is not necessary in the serial version of my code). Thanks for pointing out to this! -Simon Wolfgang Bangerth schrie

Hi Simon you can write function of setup_system like other tutorial setp, after refine mesh, rerun function of setup_system(). Best Chen Simon 于2024年6月10日周一 14:13写道: > No, the program that produced the error is serial not parallel. > > Best, > Simon > > Wolfgang Bangerth schrieb am Montag, 10.
