I haven't done step-75 but I will look into it today and take a shot at it. There is nothing special about the way I did it besides that step-37 came earlier so I had already done it and was familiar with that method. Thank you for your time and suggestion. I'll give an update probably in a day

Here is step-37 with minimal changes. All that was changed was in the creation of a DG DoFHandler and the fe_system and constrains and what not to go along with it. Then of the functions only the LapalceProblem setup_system() function was altered and nothing else. It was just altered to also be

Yes of course. I can get one with minimal changes made to step-37. Full code do you want the entirety of the changed step-37 code or just the LaplaceProblem class or just the setup_system() function? On Tuesday, June 27, 2023 at 10:53:04 AM UTC-6 peterr...@gmail.com wrote: > I'll try to take a
