Vacuum Level Limits in Molflow

Hello everyone,

I’m looking for help with a basic question with respect to Molflow’s capabilities. It appears that Molflow serves as a simulation for ultra-high vacuum, but I was curious what are the limits to where other software or analysis methods should be used? In other words, does Molflow work for rough vacuum conditions or less extreme vacuum pressures than ultra-high vacuum?

Thank you

Molflow is valid when the Knudsen number is over 1. In a typical vacuum geometry it’s below 1e-3 mbar.
