Reply To: How to Display Radiation in APDL?

Hi Dlooman,

Thank you for your reply and suggestion regarding the use of the Radiosity method and the surface load label rdsf for modeling radiation. I understand that this method might offer more accurate results, but I would appreciate it if you could elaborate on how exactly it is more accurate compared to using the SURF151 element.

Indeed, I am modeling the radiation using the surface element 151 with keyoption (9) setting. I currently use SURF151 because it allows me to easily calculate the heat flux exchanged between each surface and the extranode. Calculating this with the rdsf method is as straightforward. Could you provide more insights or examples on how the Radiosity method handles this aspect?

Thank you for your assistance.
