Variable L in VSM - looking for a simulator model

Any one where is the variable inductor in proteus VSM. I'm looking for a simulator model

a thing to note about proteus spice sim


when you want to model an inductor

simply place the inductor part

and open the component to edit it

then tick the attach hirachie module

close the edit window

pass over the component with the mouse in the center of it

and press on the keyboard ctrl X

then you will be taken to a blank
dsn schematic layout {the upper circuit {as opposed to subcircuit }

much like an inductor rises from a plane....

the plane being the part


so....

to make an inductor model in a vsm

you use R and C to determine L

by using bridging RC theorie

then combinations of R's and C's and other upper models using the mutual= properties for coil stage couplings between models within models

{for complex inductors}


for simple inductor a single R and C

is all that is needed plus a define to give an overall value state relative to resonace and reactance ....

where appropreate....
all relative to or as a means of setting /adjusting in time the actual
overall L of the coil

moreover to vary L you simply vary c relative to R

and R relative to C by r and c

so R + - r relative to C + - c
