a HFSS error for help

my HFSS gives a unexpected error:

[error] Discrete solution, process solver : subprocess "%3" died unexpectedly.

in detail, the error prompted without finishing my solution, if I re-run it, it will go a little fruther, but the error will still come.

what's the problem?

thanks!

hi
I received the same error. having checked my design several times, I realized that I had put one of my object to wrong place.
you had better control whether you connect all parts correctly or not.
send you project, one may help to check it.

Another possible cause is the mesh file too big, or maybe your harddisk and ram run out. For HFSS in windows os, the maxium allocatable ram is 1G, in unix is 2G.
