[deal.II] Re: Smooth particles hydrodynamic implementation in DealII

If I may suggest, at that point, I would ask you what you are trying to specifically achieve? If you want to build an SPH code from scratch, this is definitely possible to do using deal.II particle classes (esp. with the exchange and update ghosts functionalities), but this will require a lot of

Markus, how do you define dofs_per_face? Do you adjust it for the polynomial degree? Best W. On 2/11/22 10:51, 'Markus Mehnert' via deal.II User Group wrote: *** Caution: EXTERNAL Sender *** Hi everyone, Instead of prescribing classical Dirichlet boundary conditions (i.e. the values for t

[deal.II] Impose values inside a material/ not on the boundary

2022-02-11 Thread 'Markus Mehnert' via deal.II User Group
Hi everyone, Instead of prescribing classical Dirichlet boundary conditions (i.e. the values for the solution field on the boundary) I am trying to impose the values for a specific degree of freedom inside my material. My idea was to iterate over all cells and their faces. Then I use the locati

Dear Wolfgang, Thanks very much for your advice. I definitely should and will follow that. But may I still narrow my question for a clarification (with upcoming complexity), and as a quick question ask if adding the boundary term through cell_rhs +=... (as above, and very similar to step-7 in term

[deal.II] Error in Parallel version of Step-26

Dear All, I am trying to execute step-26 (Heat Equation) in parallel with adaptive mesh. I could execute the code with 1 processor using mpirun and if more than one processor is used, the program returns the following error message ---
