Can't get a print of voltages between nodes from this SPICE (NGSPICE) simulator.

The code is here,
Diode Voltage Drop
r1 1 2 10k
r2 2 3 5k
r3 3 4 4k
r4 4 0 3k
vin 1 0 dc 10
.print dc v(3,2)
.end

As you can see I am trying to get a voltage drop between node 3 aand 2. But the print function is not working properly. It is just showing the usual outputs of( the ouput is attached with documents). How am I supposed to fix this?

Most people on this site use LTSpice. Not sure how many use NGSpice.

Btw, these are resistors.

I dunno. LTSpice doesn't seem to support the .print v(3,2) syntax. It does (as a plotting function) if you do a .dc swept analysis, but there seems no way to do it in a .OP analysis without adding an extra node driven by a behavioral voltage source whose function definition is V=V(3,2) or V=V(3)-v(2)

Diode Voltage Drop
r1 1 2 10k
r2 2 3 5k
r3 3 4 4k
r4 4 0 3k
vin 1 0 dc 10
.dc vin 0 10 1
.print dc v(3,2)
.options NOACCT
.end

You need to run the dc analysis first. The output of plain ngspice-28 in batch mode then is:

Circuit: diode voltage drop

Doing analysis at TEMP = 27.000000 and TNOM = 27.000000
