Hi there, I'm andrew saad a master's degree student at the british univeraity in egypt I'm working on a project where I simulate the parabolic trough system where the solar radiation falls into a concentrator and it is then reflected to a receiver tube. I want to simulate the concetrator to be a reflecting surface for the solar radiation. I've tried many radiation models but none of them achieved that condition so my question is how to set the parabolic trough surface to be as a reflecting surface for the solar radiation on it Thanks and regards, Andrew
