Helmholtz equation error
Posted: 23 Mar 2021, 06:44
I am having trouble getting my acoustic waveguide simulation to run. Attached is the cif file and a .unv file if anyone wants to load things from scratch (Just run the .unv file through ElmerGrid 8 2 to get an Elmer mesh file). I keep getting the error shown below and don't know how to fix it. There also seems to be an error in the time stepping setup. I suspect that I have messed up my Driver BC.
Any help would be sincerely appreciated.
