[deal.II] Re: function face_component_to_system_index() for Discontinuous Galerkin ?

2021-09-23 Thread Sylvain Mathonnière
I wanted to add some clarification: I realised that what I called *n_vertices* is missleading, it is not the number of vertices I want but the number of "nodes per cell". Numerically, it is however correct if *FE_DGQ(1)*. More generally, it should be something like *n_nodes = (fe_eq1.degree+1)

Prof. Kronbichler First, I would like to thank you for the development of matrix free library. Sir, I am extremely thankful for your response. I have modified the procedure and it's working perfectly. I am simulating the evolution of Zr-delatH under mechanical loads by developing a phase field m

I did not check all code in detail, but what I observe is that you write into the joint_solution vector without ghosts. Now this would likely result in a run time error (for countinuous elements and in debug mode), rather than wrong output. But either way, I would recommend you move the "locall

Dear all I am using dealii to solve a multi component system has its own fe, dofHandler, and solution vector. I am using a matrix free implementation for the entire program. I am using the Postprocessor class to derive quantities that depend on all of the components. The Postprocessor wo

Hei, I will do that as soon as my re-compilation is done. I re-compiled deal.II with gcc 11.2, and in that case I did not get a segfault. Thus, I will now try to narrow down the issue if it might be related to the intel compiler, or not. Regards Matthias Maier schrieb am Donnerstag, 23. Septemb
