solar ray tracing and do irradiation
 
what is the difference between solar ray tracing and DO irradiation in solar load model ? and how to use this two solar load model ?

Hi

Did you found the answer to your question? right now Im confused about which one to pick...

ANSYS Fluent provides a solar load model that can be used to calculate radiation effects from the sunís rays that enter a computational domain.

Two options are available for the model: solar ray tracing and DO irradiation.


The ray tracing approach is a highly efficient and practical means of applying solar loads as heat sources in the energy equations.

In cases where you want to use the discrete ordinates (DO) model to calculate radiation effects within the domain, an option is available to supply outside beam direction and intensity parameters directly to the DO model.
