The DIAC element in the circuit -- need help

Hi. I am trying to simulate the circuit from:

which uses DIAC. The purpose of the circuit is to flash the LED light when the voltage is in the range (e.g., 200 Vdc to 1000 Vdc), where the flashing frequency would increase with the voltage.

However, when implementing the circuit, I do not get the expected output.

I noticed for DIAC in the library it says [Non-Simulatable]. Does it mean the element does not work?

Any advice on how to make it work and make the circuit work?

My circuit is here:
