[deal.II] Re: Relation between Solution Error Behavior and Polynomial Approximation Degree

Hello Jaekwang, I am trying to generate some log-log plots, and wondering if you used the functions in deal.ii to generate the figure. If not, what did you use? Thanks, Jiaqi 在 2016年9月29日星期四 UTC-4上午11:41:48，Jaekwang Kim写道： > > >

Guess I figured it out. I didn't do constraints.distribute(); 在 2017年3月23日星期四 UTC-4上午1:38:32，seven写道： > > > Hello all, > > I am trying to project a solution in FE_DGP(sol_dg) to FE_Q (sol_cg), but > I only know the gradients of sol_dg and its values at some vertices, so

[deal.II] Vertices constraints inside the domain

Hello all, I am trying to project a solution in FE_DGP(sol_dg) to FE_Q (sol_cg), but I only know the gradients of sol_dg and its values at some vertices, so I want to fix values of sol_cg at the same vertices after the projection. The first method I tried is quite straightforward, but the resu
