Hi all, I am currently trying to work out how to export an LTSPICE model to CST. Just to get how to do it basically I have started by just using a standard 50 ohm resistor that I want to export as a .net/.cir file that will be accepted by CST when I try to insert it as a general circuit through the lumped element option. I have a model in LTSPICE where I have set up ports labelled 1 and 2 but CST says "Lumped element circuit simulation: SPICE file needs to have exactly one 2-terminal subcircuit."

Has someone got an LTSPICE model that they have got to work with CST? If so how have you set up your terminals on it so that CST doesn't bring up this warning?

Thanks!
