solidworks flow simulation to analyze the performance of prabolic dish

Question asked by Ahmed Walid on Apr 25, 2020

 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
