Mats:
I finally got your run to complete after 7 hours. I like your methods very much.
I had never experimented with the excluded elements. I think that will be a very useful function for me. I'll start tomorrow continuing with your model to see if I can adjust the material to get reasonable results. I'm open to suggestions for this as well.
As far as run time... This took much longer to run than expected. I have a 3.7 GHz, 16 GB RAM desktop and I have the SOLRAM set to 8000 MB. Anything else I need to look at that may be able to increase speed?
Thanks,
Chris
