[deal.II] Generate explicit instantiations for a new member function

Hi, I have the need to create a new member function in the MatrixTools namespace. Basically, I need just to create a new function which is almost identical to another function which is there, except for 2/3 lines. I declared my function in *matrix_tools.h *and define it in the *matrix_tools.c

Thanks Marc for your answer. I should have given more context, as maybe in this particular case things can be simpler. I'm using compute_point_locations() and so in my code I have: *aut

[deal.II] Re: Obtain degrees of freedom starting from the cell

Hi Marc, there's a problem: that function assumes that you do the usual cell->get_dof_indices(local_to_global); In my case, I only have the integer number associated to that cell, say 80, and I wanna know what are the DoFs associated to cell number 80 of my triangulation. If it's not clear, I

[deal.II] Obtain degrees of freedom starting from the cell

Hi everyone, I'm in a strange situation at the moment. Basically, I have the number of a cell in my triangulation, and I want to know the degrees of freedom associated to that cell. Namely, given the integer number associated to the global cell, I'd like to know the global numbers of the DoFs a

[deal.II] Apply boundary conditions using the method of lines

Hello, I'm trying to solve the 2D heat equation with the method of lines, instead of Rothe's method as explained in the tutorials, as I'd like to use ARKODE to march in time. Assuming that the *boundary data is 0* and the initial data is *x*y*(1-x)*(1-y)*, after writing the weak formulation, I

[deal.II] EOC for step-12

Hi everyone, I'm expanding step-12 in order to practice with DG. As written in the possible extensions, I should observe order p+1 in L^2 norm if I refine uniformly the mesh. So I decided to use the *ParsedConvergenceTable *to check the right EOC. I have built a manufactured **smooth** soluti
