It works for me. That "open circuit" message isn't always a problem. It means there was a matrix singularity, which could be during iteration and not a final result. "open circuit" means that there is a high impedance at a node, so high that it is impossible to calculate a voltage. For example, think of two capacitors in series. What is the DC voltage at the junction? it's unknown! I don't see anything like that for your circuit, but when not converged anything can happen. _______________________________________________ Help-gnucap mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gnucap
