Kinetic energy filter surface

Hi,

I’m new to gromacs. Is there a possibility in it to make a surface that acts as a particle filter, letting through only particles that having a kinetic energy above a certai value?

The surface would selectively let through a simulated particle colliding into it based on its kinetic energy - if the particle has a kinetic energy above a certain (user defined) threshold, it will pass through the surface and if it doesn’t it will bounce back from the surface.

Thanks!

GROMACS does not support this kind of feature.

Ok, thanks anyway.

Cheers,
Antti
