Thank you for your kind reply about software licenses.

We are considering how adsorbed molecules on the wall are detached by molecular collisions.
We would like to know how to set it with Advance Facet Parameters.

Thank you and best regards.

Hello.

Sorry, I realized I never replied to this.

If the issue is still current, could you explain a bit more the process you're trying to simulate? As far as I know, in standard circumstances molecular collisions don't detach absorbed molecules (unless they are ionized, or of particular high energy).

In what setting would your molecules desorb from the wall?

Usually Molflow can't solve problems where the desorption or the sticking depends on the system state (these cases would require iterative simulations which are not yet supported).
