Hi Flash User Group,
I was trying to see how chamber size would affect the pre-plasma generation in the LaserSlab example problem. The problem I ran into is that the AMR mesh between the two simulation runs had different mesh sizes even though in the flash.par file they had the same lrefine_max and set to be equal. I attached both the files above. An example of how the two simulation runs look like in visit can be seen here (Fig A, B). I have also put an example of how I believe the mesh (Fig A) should look (Fig C). I know I can just create a regular cartesian mesh with i,j,k procs but that would lead to longer runtimes without the AMR so I was wondering if there was any manual way to set the different AMR sizes based on like height in the z-direction in an R-Z problem.
