Hi I am running fastcap with the following setup 5 parallel conductors with a ground plane (also a large sheet of conductor) under the 5 parallel conductors. However, I keep on getting some non-negative off-diagoanl in my capacitance matrix. If I removed the conductor, I will not ahve this problem. Anyone know how to get around this problem? Thank you in advance Regards, Andy Kuo ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
