3d vof
Hello,
Need help :( I am getting this problem with the 3D VOF (air jet impinging over water). The simulation is good till 1.4e2s but after that it gives the following error. The time step size i am using is 1e6 with 40 time steps. The setting are as follows: 1. Double with SST 2. Surface tension 0.073 n/m 3. inlet velocity 96.672 m/s 4. PISO Scheme with VF(Mod HRIC) Momentum (2nd ord) 5. URF Pressure 0.3 Density 0.5 Body Forces 1 VF 0.5 In 2D for the same thing, i had mass loss problem but i was able to find the solution with the help of few people here. Would be thankful for your kind reply.

Forgotten the show the geometry. Its the same for 3D case
