ray-tracing solar load vs DO radiation model

nima_nz · October 9, 2015, 10:00

Hi
I'm confused in using ray-tracing solar load model and DO radiation model.
When we use the ray-tracing solar load model to simulate the solar load on the semi-transparent wall (eg, glass window), If DO radiation model enabled, in boundary condition menu at radiation tab, we should specify the value for Irradiation; If determine a value for irradiation there after solution converged, in the results, it seems the software affects two irradiation separately in the solution (one from solar load and another from irradiance which determined at boundary condition). What should we do in this problem? An idea is finding transmitted visible irradiation from ray-tracing and after that disable the solar load model and determined that value in the boundary condition's radiation tab.
Thanks for your help.

hello nima
are you working on concentrated solar energy or flat plate?

You know, I want to model the solar energy penetrated through glazing in the building, but it doesn't work properly.

Hello, Nima.
Are you working and analysis the concentrated solar energy or flat plate? I am also...But i do not get any idea of it, as I am new beginner of Ansys. Can you sharing some information with me?

Hello！
Use solarload in chtmultiregionfoam and select sundritracking. Why does the temperature rise again until the sun sets completely?
