If you want to use BEM, then also take a look at step-34, and at WaveBEM. Luca > Il giorno 9 ott 2024, alle ore 01:45, Wolfgang Bangerth > ha scritto: > > On 10/8/24 12:19, Tim Braun wrote: >> ** >> I'll add that I see step-70 as an example, which is time-dependent but does >> address the c

Wolfgang, Thank you very much for your willingness to look into the issue. I made a github issue. I couldn't upload a .cpp source file, so I included the example as a code block. Regards, Kyle On Tue, Oct 8, 2024 at 12:05 PM Wolfgang Bangerth wrote: > > Hi Kyle, > > > I have a quick question.

[deal.II] FSI with separate grids.

2024-10-08 Thread Tim Braun
I am designing a study of elastic responses of structures underwater. An important aspect in calculating vibration is the added mass (effect of accelerating the incompressible fluid around the vibrating object). Instead of using a transient FSI setup, I am seeking to solve the potential flow ar

Hi Kyle, I have a quick question. Should I be expecting FE_Simplex of cubic order to work in an FESystem? In case the answer is "yes", I'm attaching a minimal example that I would expect to work, but it fails some assert in the library. I tried checking, but could not really understand why t
