Hello, everyone
I met a problem when I using the cfx to calculate a 3-D cascade flow conjugate heat transfer problem. when I only consider the convection and condution, the cfx-solver can work and I can get a result. But when I add the radition, the cfx-solver can not work. The radiation model I used is the Discret transfer model, the spectral model is weigthed sum of gray gases. The cfx-solver stopped and the .out is as blew: Radiation Coarsening Information Domain Name: Coolant Domain Target coarsening rate = 64 Number of fine grid elements =2473259 Number of radiation elements = 44048 Actual coarsening rate = 56 Domain Name:Hot Gas Domain Target coarsening rate = 64 Number of fine grid elements =5905449 Number of radiation elements = 114592 Actual coarsening rate = 51 ERROR #001100279 has occurred in subroutine ErrAction. Message: Stopped in routine SU_SURF_TRI_3 Does anybody know where the problem is and what I should do to get a result. I hope I can get help here and Thanks a lot. |

I would try different coarsening rates. Just a guess, but easy to try.

You can try:
1. Make sure you are not using an old version of CFX 2. If you have a thin surface, split the two sides to appear in separate boundary conditions. |
