[deal.II] Solving Step-74 by MPI

Dear community, I have a problem in the assembly part when solving Step-74 (DG method) by MPI. Generally speaking, we can first determine whether one cell is locally owned or not by cell->is_locally_owned(), and then assemble matrices and residuals by hands (e.g. Step-40 for CG and “Distributed

[deal.II] How to consider 1D fracture flow in a 2D domain?

configurations (like 2D for solid deformation and 1D for fluid flow)? 4. Is there any example in the tutorial related to my problem? I will be grateful for any help you can provide. Sincerely, Chong Liu -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum o

Re: [deal.II] How to consider 1D fracture flow in a 2D domain?

Dear W. Thank you for your suggestions. I will look at step-60 and step-70 and find a way to solve my problem with mixed triangulations. Best wishes, Chong Wolfgang Bangerth 于2021年3月3日周三 下午9:25写道： > On 3/3/21 10:30 AM, chong liu wrote: > > I have several questions about how to impl
