Default Turb. Kinetic energy

Hello,

can you please suggest me how to define the Turb. Kinetic energy and Turb. Dissipation rate ? If I leave the default value (1), then the turbulence viscosity ratio warning appears several times. If I set a value much lower, the message does not appear any more. But I would like to understand how to properly set these two values.

Thank you

it is better to start simulation with high value of k and epsilon.try k=.1 and epsilon=.25 for ur simulation.
