have you tried gnucap?
You will need the spice-diod
By component sizes do you mean the parameters in the model?
It might be instructive to compare the parameters in a "normal" diode
model with those in your zener model to see if there are any you could
add to see if they improve the behaviour.
The idea of using a V source with a series diode and a
I have not used a parallel gig ohm resistor or series inductor, but I
have tried tweaking component sizes and it is extremely hard to get
zeners to not gag in the middle of a transient sim I was looking for a
very generic all purpose model that won't yak. It doesn't haven't to

Hmmm.
Tricky things zener, schottky and soft recovery diode models ...
Try a different vendors model (check to see if it is actually a
different model)?
You could try using a V (voltage) source in series with an ordinary
diode plus a second diode in anti-parallel with the series V and
diode.

Does anybody have a nice and simple zener diode model they would like
to share? The model that I am using has trouble with convergence in
context of a complicated switching circuit with ngspice.
