Problem during simulation of mixid fluids ( solver: buoyantBoussinesqSimpleFoam)
Hello, i have a problem during the simulation. At time step 120 appears this error:

Can someone help me?
the case consist in mixing of two turbulent flows of water at different velocity and temperature, in correspondence of a curve at 90 ◦ of a to duct. The solver is buoyantBoussinesqSimpleFoam and the model of turbolence is k − ε |
