Tips of independent current sources...where are they or how to make them?

Ah, Ipoma I think you want to refer to this topic (its not my topic) with what your wrote now:

Zero value resistor

How come a zero value resistor is not supported? It took me awhile to figure out this was a problem and resulting in cryptic nan(ind) reported node values. The documentation does’t indicate 0 is not supported. I don’t recall this being an issue in other spice, or is it? Does one need to use {GMIN} or something?
