[deal.II] A small question about subdomain renumbering

Dear all, I have a question about DoFRenumbering::subdomain_wise(dof_handler). In step-17 tutorial for example, this function doesn't use the argument of n_mpi_processes, how does it know how many subdomains it should divide the dofs into? After we renumbered the subdomain and get the

The best way to proceed is to set the boundary conditions using Physical Entities in GMSH. An example is always better. For example, the following GMSH code : lc = 2.0e-1; lf = 2.0e-1; RO=1; RI=0.25; Point(0) = {0, 0, 0, lc}; Point(1) = {RO, 0, 0, lc}; Point(2) = {0, -RO , 0, lc};

Hi, Wolfgang, Thank you for your reply. The complete code can be found on GitHub and we also have the instruction for compiling the code on TACC in UTA. This code is in the branch thm_seg_distributed. You may like to download it and build it.
