Absolute beginner cannot run a simulation because the ground is floating. For ground
I'm supposed to place 0/SOURCE, but I cannot find that in the library.

Also, I'm getting exactly the same library offerings in Place > Power... as in Place
> Ground.... That must be wrong?

PSpice as any Spice based simulation program requires a DC path to
ground. Therefore, you need to place (and connect) Ground (node 0)
somewhere into your design...

If your design is meant to be floating, insert a high value resistance
which should not affect global functionnality.

Hope this helps.

In the ground library should I not have an option to choose a part called O/SOURCE?
I believe the symbol is a the regular kind of (lined) triangle shape with a 0 next to
it. I just placed the regular ground symbol that comes up without the 0 because that
was the nearest (GND/CAPSYM). Where is the O/SOURCE ground I wonder in the library.

Cannot see that.

When I go to Place > Ground... I see the following part options:

GND
GND_EARTH
GND_FIELD SIGNAL
GND_POWER
GND_SIGNAL
VCC
VCC_ARROW
VCC_BAR
VCC_CIRCLE
VCC_WAVE

You must be using "Capture", gag me with a spoon ;-)

Any of the "ground" parts produces a node name of "0" (zero).

I just looked at some basic tutorial and it had me start up "Capture". That did not
work on the analysis, so I've gone to "Schematic". I think the analysis is working
here.

No it doesn't, you have to couble click on it and rename it to 0.

That's funny, it creates a node name of "0" (zero) here (with
Schematics). As I said above, "You must be using "Capture", gag me

When I had my students install the Student 9.1 release (Capture)
sometimes the Ground/0 is in the "Place Ground" and sometimes it's
not. Adding the EVAL or Source Libraries by hand (in the same Window
you get to after selecting "Place Ground" from the Palette) brought it
back in the available parts.
