Solar Loading Model Fluent

[@hangxu5332]

thanks for sharing!I have one question.For low-x-hotwall wall,it is velocity-inlet type,but you do not definite the velocity,so the Fluent has warning:Flow boundary zone found adjacent to solid zone.how do i solve this problem?

[@siddharthbhayani1826]

Excellent work... If possible share full video for it.. Because in this video you crop some part off setup step..

Sorry but I only have this video

[@alb8350]

hi, nce video and explanantion but when I repeat your exercise all in in blue...do you know why? i am looking for irradiation on the external surface rather than internal. could you please help me? it is like your last example where you have issues as well

[@Dz8598]

thank you, i have a question. you showed the solar heat flux contour on FLUENT, but not CFD-post. Is it possible to see the solar heat flux contour on CFD Post? because in fluent the solar heat flux can be displayed but in my CFD post its not showing.

[@NazmulHossain-nb4lc]

CFD post will only show the parameters you have saved for post processing. For transient problem, it should be in the calculation activities>automatic export section...for steady-state, try clicking on the File>Data quantities in Fluent and add the heat flux as a data you want to save for post-processing

Excellent tutorial. Could you please explain the mesh orientation ?? which point is (0,0,0)? May I know why you put Z= -1 in north ? Thanks in advance.

[@NazmulHossain-nb4lc]

(0,0,0) is one of the bottom left corner of the geometry . I think the best way to explain is x-length, y-length and z-length are all in positive direction. Now, I put z=-1 in solar ray tracing model to specify the angle of incident of solar flux. You can select any value of x,y and z in solar ray tracing option. However, make sure the angle of incident calculated from those value are your required incident angle. Its a simple calculation, like, tan(theta)=height/base

Sir I not have the option of solar load model in ANSYS, why?

[@NazmulHossain-nb4lc]

I am not sure either. might be a fluent bug. try pasting this in the console. maybe will work. define/models/radiation/solar? y

@@NazmulHossain-nb4lc Thank you sir, the issue was resolved.

I am getting an error while working on a model(results are same like yours) can i get your email address!!

[@NazmulHossain-nb4lc]

what kind of error are you seeing? I would rather answer your question here so that everyone can be benefited.
