Does anyone have any preferences on where to stop the steping? Should I just do something relatively big, like 300? Below is Marhsall's response about the hangup that he created... -Peter -------------------------------------------------------- Hi Peter, my mistake, it was definitely the one I loaded Mon morning (been so busy with the NSF I forgot I was even at MIT on Mon). I had about 3 simulations running. I think it was either sharing rate (4), elites (2), or inferior switch (5). MVA Quoting max...@ya...: > Yeah, that's what I was thinking.
