What do following messages mean?!
Float overflow exception in simulation.
Warning: singular matrix:  check nodes lakt1#branch and lakt1#branch
Warning: source stepping failed
doAnalyses: Matrix is singular
thanks

You most likely failed to include "ground", a node numbered 0 (zero).

Most "Spices" tend to give utterly meaningless error messages... just
like Windows ;-)

You may have a floating node.

"Matrix is singular" -- plus the 'node' being the branch current
equation associated with an inductor.... Makes me think either the
matrix package didn't manage to remove the zero from the diagonal --
do you have a tree of inductors? -- or that you have a voltage
source/inductor loop.



Re: Spice Error Masseges
Yes, I have a Transformer and an inductor in my circuit.
