Hi,
doing some test with "blast.cmd" (2D), i.e., cgcns with AMR.
Grid is simplest possible, just "rectangle" (and no internal structures).
Initial data given by "bubbles", just one, but it is placed so that only
a quarter of it is inside the domain (i.e., origin of bubble sits at one
of the corners of the "rectangle").
All four boundaries on mesh are slipWall. This set up should (I think)
generate a solution of a cylindrical shock propagating through the
domain. The issue I see is that when AMR is on the refinement of the
grid is working differently close to the boundaries, e.g., using nrl=2
the refinement is lacking over the part of the shock that touches the
slipWalls. This leads to a more "smeared" shock with slightly lower peak
value close to the wall.
When running without AMR, but with a resolution corresponding to the
refined AMR-mesh I don't see the smearing close to the walls.
Are there possibly some settings regarding AMR one could use to improve
this situation?
Thanks,
