Radiation Modeling

Raju

Hi Team, I am trying to use Monte Carlo Radiation model, but finding problem in solution startup due to very high mesh size (8M). I am trying to reduce the number of radiation elements thorugh advance solver control radiation option. ie. like varying the "target coarsening rate". While doing this i came to know that other two parameters which affects the "target coarsening rate" : 1)minimum blocking factor and 2) maximum blocking factor. If anyone knows the relation between these three variables ("target coarsening rate", minimum blocking factor and maximum blocking factor), please let me know.

Thanks in advance.

Raju.
