Applied patch and no effect at all. For a simulation of 1 065 600 cells made of air, meep consume 357 MB. The same with 345 600 cells made this time of a material (two different in fact, but both with 3 polarizability) with 3 polarizability, meep consume then 1.2 GB Both checked with and without the patch. No difference at all. And checked again. This patch should be for something else. Cheers. -- _______________________________________________ meep-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
