A few simple questions that I had regarding vectors: 1) How can I initialize them to a particular value? Can i just resize them to n_dof and then add a scalar? 2) Would the correct way to re-assemble my vector be - GlobalVector.add(local_vector, dof_map_indices) (the same way while assembling the system matrix)? 3) How do I write out the vector using the Tecplot_IO? If I pass the equation_system reference to the IO object, would it also write out the vector?

Depends on what you mean by efficient ; clearly that requires more storage but usually provides a speed benefit because you do not need to repeatedly recalculate the primitives. -Ben On Jul 15, 2014, at 1:53 PM, Sahai, Amal <[email protected]> wrote: > I have a compressible flow solver that solves for the conservative variables. > I was wondering what would be the best way to store primitive variables? > Right now I have attached a vector to the system that I solve and I update it > after every iteration (I assemble it the way the system matrix is assembled). > Is this the most efficient way to get this done? > > Regards > Amal > ------------------------------------------------------------------------------ > Want fast and easy access to all the code in your enterprise?
