Spark Gap - Please Help

I'm using Multisim 13.0 and need to place a spark gap device. I've heard set the ignition voltage on a neon bulb, no neon bulb. Then set the voltage conduction of a zener diode, which one and how? Multisim has been around for some time now and their is no fix for this issue? I'm not a happy camper right now.

What is the particular issue? One component missing? Also if you want to make a suggestion to improve NI Multisim you should post your concerns in the idea exchange forum:


Do you have any doubt about one of the steps of the custom components creation process?


This particular issue was discussed on a old forum in which another person shared his model and his ideas:


This forum was answered by Tien P, who has a lot of experiece in NI Multisim.
