Hello everyone, hope everyone is doing fine and simulating well. I am here today with an issue related to radiation model which I just started getting my hands on. My problem statement is described as below:


I am trying to simulate an Urban Farming module with a 78 million cells and 44 million nodes. In the domain the Urban Farming module is surrounded by buildings and ground where shell conduction b.c is applied. The complication arrives when I switch to solar ray tracing model along with DO model used as the radiation model. Until initialization things are so far so good but when I try to run the simulation it gives an error " Divergence detected in DO intensity". But when I switch off the solar load or switch to Solar Irradiation model and run simply with the DO radiation it is running fine. So, now my doubt is what really is happening with the physics involved that it is running fine with Solar Irradiation model and not Solar Ray Tracing model? Or what is the absolute distinction between these two solar load model?
If anyone is aware or have any slightest idea about the problem please let me know, will be of great help.
Thank you
