mapping beteween loc_index and global_index
I noticed that there is an output parameter N_loc in the construct_init function. I'd like to understand the purpose of this parameter. Does this parameter correspond to each process's local index range (1:N_loc, 1:N_loc)? And can we use the msh%new2old() interface to obtain the global indices, which would correspond to the index range of elements that each process needs to retrieve through the element computation function during the compression process?
