Hey everyone

I am modelling a solidification problem where I want a reflection criteria for the discrete phase particles. I want these particles to get reflected from an iso surface just like the action of a wall on the particles. Is there any way of making an iso surface (in this case it will be a surface having liquid fraction of 0.3) as a "wall" for the particles for which I could possibly write some udf? What will be the macros for this?
