Hi All,

I'm a new member of the forum and an engineering student working with CFD for the first time. I'm new to this so please be patient with me. I work with ANSYS 14.0.

My task is to model a lamp in a duct/box and establish a radiation field with some flow going through this contained space. I've already setup my geometry with inlets and outlets with the lamp in the middle and solved the velocity profiles. My problem is then working with Discrete Ordinate Radiation (DO) emanating from the lamp.

I've tried looking at some manual for basic DO radiation application and followed it quite closely. I found though that my final radiation field looks like a flower (bare with me..). This is very strange as the lamp shape I used is circular so I expected the radiation field to be circular as well. I should probably post some pics.. ** I will do that soon..**

Is there something wrong that I did? Is this a common problem with DO model?

Thanks!
