Here, is my code>( latest code of Adaptive Poisson DG)
Poisson_adapt_refine.edp (5.3 KB)
I need results as in the following table>
I am trying to verify the results of the first Example of the following paper:
Numerical Methods Partial - 2019 - Cui - A posteriori error estimate for discontinuous Galerkin finite element method on.pdf (1.7 MB)
I have used the following tutorial code:
Any help is this regard will be useful for me. I am not getting why good results not coming as in the above table.
Thanks in advance!.
