Hello,
Need help I am getting this problem with the 3D VOF (air jet impinging over water). The simulation is good till 1.4e-2s but after that it gives the following error. The time step size i am using is 1e-6 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.
