[sparta-users] surf/move

[Madan B K <mad...@wm...>]

Hello SPARTA developers,
I have a question about how particles interact with moving surfaces when using the fix move/surf (and fix move/surf/kk) command.
When a surface element is moved using this fix, do particles bounce when they collide with the surface (as in the usual reflection model), or are they deleted immediately upon contact — as if they vanish as soon as they intersect with the moving surface?
I’m trying to clarify whether the particle-surface interaction is handled dynamically (reflective) or instant deletion when overlap occurs during motion.
Thank you for your time and for maintaining SPARTA!
