Hi There DSMC folk -

I was thinking about trying to modify one of the wall interaction models to make it a vacuum boundary. I don't have a lot of c++ experience, but in a Fortran90 dsmc code that I have used there was a wall interaction model that basically just a removed a user specified percentage of incident particles while the rest were reflected back according to the wall model (specular or diffuse).

Does it seem possible to just "delete" a percentage or all incident cloud particles? Any thoughts on how this could be implemented?

Thanks.
