Yes, you can do that. You'll have to define the dependent variables across both the domains and map the variable values over at each sweep / timestep so there will be some overhead. -- Daniel Wheeler -- To unsubscribe from this group, send email to fipy+unsubscr...@list.nist.gov View this message at https://list.nist.gov/fipy To unsubscribe from this group and stop receiving emails from it, send an email to fipy+unsubscr...@list.nist.gov.
