I'm trying to learn/understand the linear multigrid (mglin) routine.

In the example driver for mglin only the results from grid level 3 (9x9) are printed out even though gird level 5 (33x33) is specified. Is there a particular reason for this?

Thanks

Hi,

The results from the finest step are in fact printed out, but only every fourth grid point is printed. This is so that the results will display nicely as a rectangle on the screen.
