Hello fluent users ,
I appreciate your time and effort to help others solve their problems .

I work on radiation and convection modelling of a solar receiver for Concentrated Solar Power (CSP) tower systems with DO radiation model and i think i should use one of this solutions :

1- Model a solar irradiation source field by defining semi-transparent walls at the boundary of the computational domain. Each wall reflecting solar irradiation at a specific specular angle. By dividing a plane into many subsections, and assigning an irradiation direction to each that is pointed towards a specific target .

2- write UDF for gaussian distribution heat source with given maximum value as boundary condition on this semi-transparent wall and set the directions toward a target .

3 -( bailout plan less realistic ) set a uniform solar irradiation on a semi transparent wall and set directions toward a target

i will be very grateful if you teach me how to apply one of this solution in order to solve this problem .

Thank you
