I have the following LTspice simulation schematic. (It's a simplified version, just to demonstrate my dificulty). The LTspice simulator returns a paralleled voltage sources error even when the sources V5 and V6 are clearly not in parallel. Is there any walkaround that avoids putting internal series resistances with the sources? Why is this error coming up at all? I'm using the most recent version of LTspice.
Look at your node naming. That “GGL” on both will short them or draw an invisible line between them. It’s intended to make your schematic less crowded and human readable, but if you take a look in your netlist which any SPICE uses behind the scenes, they are shorted.
Solution: remove the “GGL” statement for one of the nodes or just rename it.
