fluctuations in turbulence frequency and kinetic energy

rskrishna87 · April 11, 2011, 08:24

Hi everyone,

I have a problem with the convergence of my model when i change the design of my structure to a a structure similar to flower. the problem is that i am getting lot of fluctuation in the turbulence kinetic energy and turbulence frequency. Can anyone tell me what is the reason.

Do i need to change any turbulence parameters?

Thanks in advance

Regards,
Krishna
