Hi guys. I used solidworks flow simulation to analyze the performance of prabolic dish solar collector but i fight the following problems
1- Incident solar radiation don't reflect at focal point though I choice reflector as symmetry.
2- I can't put air as Fluid subdomain between reflector and absorber.
3- In wizard settings, I can choice one material for reflector or absorber but I can't choice two types of material for reflector or absorber.
4- In default settings appear there are many choices of radiative wall , outer wall , thermal wall but don't understand which for absorber and which for reflector.
5- In goals, i don't see incident solar radiation option. Other problems don't understand and i very tired from this simulation
