collision of a droplet with a solid surface
 

Dear all, I'm tring to simulate by Flunet 5.4 an impact of a single liquid droplet onto a solid, dry and smooth surfaces. I'm using a multiphase model (VOF-GeoReconstruct) with surface tension, laminar flow, square mesh grid. Unfortunately I am findimg loads of problems in the recoiling phase. Please, can you give me some advices about this subject? Best regards. Mirko.
