Hello everyone,

I am working on analysing a building for PMV model. I am using Fluent for simulation.

I am stuck in preprocessing - finding out the mean radiant temperature. In CFD post there is one macro defined for finding out m.r.t, but it requires wall irradiation flux as input, which is not defined by fluent.

What should I do? Also in writing UDF I am having a problem. To define m.r.t. at a given point, I have to find out view factor between that point and each face element on the wall. For that, I think I need to run a loop of all face threads present in wall domain, inside a loop of cell threads present in the fluid domain. I don't know how to do that.

Please help.

Thanks in advance!!
