Hi all,

I was simulating my model for 2s. It was actually liquid splashing in a large converter (10m * 6.3m) using subsonic gas flow through a nozzle. I used k-e standard turbulence model, incompressible flow and VoF model. Initial turbulence kinetic energy was 0.001 and dissipation rate 100.

I have received 'turbulent viscosity limited to viscosity ratio of 1.000000e+05 in 1 cells' message after time step 19880 and "turbulent viscosity limited to viscosity ratio of 1.000000e+05 in 104652 cells"  after time step 107676. Then I have received the following messages. What could be reason behind of getting message?

 

Unable to parse: [free

Error: undefined read macro
Error Object: ()

Error: wta(2nd) to string_eq
Error Object: (1 cells)

 

How can I solve the turbulent viscosity ratio problem?

there may be several reasons for this. 

make sure you have selected the correct sufficiently large domain. 

please make sure that you have a good quality mesh. the min orthogonal quality should be more than 0.1.

make sure you give correct inputs to the solver.
