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?

Hi, may I ask you this question?Recently, I was doing the simulation of inclusion behavior after solidification of molten steel. The solidification part has been calculated. Now I am going to add the calculation of inclusion particles. I have encountered problems in UDF. Can I ask you for advice? Thank you. My email: 2424464575@qq.com , thanks again! Best wishes!
My questions are as follows:
When the volume fraction of liquid phase encountered by the particles is less than 0.6, the particles are considered to be captured by the solidified shell of liquid steel.
