Re: [deal.II] Re: AMR , how to pass solution vector to refined mesh

Thank you!! Just got what've meant. and fixed my code properly Thanks ! Jaekwang Kim 2017년 3월 21일 화요일 오후 12시 55분 7초 UTC-4, Jean-Paul Pelteret 님의 말: > > Hi Jaekwang, > > No, you've misunderstood in that I was just showing that to you as an > example. You don't need to use that exact Vector

Re: [deal.II] Re: AMR , how to pass solution vector to refined mesh

Hi Jaekwang, No, you've misunderstood in that I was just showing that to you as an example. You don't need to use that exact Vector class. You were nearly at the answer with what you've posted - you just need to read the compiler error more carefully to understand what its telling you is

Re: [deal.II] Re: AMR , how to pass solution vector to refined mesh

thank you for your response. I am trying to following this... but it seems that I have to use the class, * SolutionTransfer* to transfer block vector Without using MPI, isn't it possible to assess this class? like...

Re: [deal.II] Re: AMR , how to pass solution vector to refined mesh

Dear Jaekwang, Step-31 demonstrates how to use the SolutionTransfer class with BlockVectors. In short, you need to specify the vector type as a template argument to the class. Here's how its done in that tutorial:

Re: [deal.II] Re: AMR , how to pass solution vector to refined mesh

Dear. Dr, Bangerth Adding up to this, I want to ask one more question. I was trying to transfer 'vector-valuled' solution (Block vector type) as I did for scalar solution (Vector type). but it seems that the command line *solution_transfer.prepare_for_coarsening_and_refinement(solution); *

Re: [deal.II] Re: AMR , how to pass solution vector to refined mesh

Thank you ! You just pointed out exact problem that my code had! I was not taking into constraints when I make new sparsity pattern! * DoFTools::make_sparsity_pattern(dof_handler,* *dsp,* *constraints,* *

Thanks for your response. I tried to assert assemble function as you suggested, but I didn't receive any error message. What make me more confuse me is the code is working with global refinement. if I input 100% cells to be refined.. GridRefinement::refine_and_coarsen_fixed_number
