Issue in interaction of particle with DO radiation
 

Dear All,

I am currently trying to heat up an inert particle using a radiation beam from a semi-transparent wall using the Discrete-Ordinates Radiation model. I have switched on the particle radiation interaction, however, the particle is not absorbing the incident radiation. I have attached the file for your reference. Could you please let me know what I might be missing? I also want to bring to your notice that I had run the same case a few weeks ago and the inert particle was getting heated(particle and fluid temperature distribution is attached), but don't know why it isn't working now.




Regards,
Subham
