Hi, I was trying to use grids with no of points as 49 in a given direction. For this, I made my nlevel as 3 (49 = 3 * 2^(3+1) +1). But I found that the simulator would revert back to no of grid points as 33 and nlevel as 4. On further investigation, I found that this lower limit for nlevel was hardcoded in the code. I was wondering if there was any way we can use nlevel as 3 or is this some hard limit imposed by the numerical multigrid method used ? gulzar |

Hi Gulzar -- You're right: I wasn't very smart about the way I hard-coded the minimum nlev -- I was basically trying to force folks to use the MG algorithm to its full capabilities for large systems; it doens't really matter for smaller systems. For your applicaiton, I would just you change the hard-coded limit in the source to 2 or 3.
