Hello everyone,

I was trying to draw a 3D geometry (solar air heater with corrugated absorber) as you can see in this picture, but I forgot to insert an angle to the solar air heater because it's inclined with 21°. when I finished the geometry I tried to insert an angle and make the solar air heater inclined with 21° but I couldn't. Please, can someone of you show me how to do this if it's possible?

I'll be so grateful for any answers from you. 

Best regards and best wishes,

Dounia

Which bit needs to be angled? You can alter the gravity component in the solver too, that may be easier?

The whole geometry needs to be angled, is there a way so I can insert an angle to the whole geometry?

In the analysis system you want to use, create a coordinate system rotated by 21 degrees about Z and use that to define gravity, or just type in the components of X and Y acceleration that define gravity being tipped by 21 degrees.

Or use the body operations (or similar) to rotate the volume(s).

I used body operations, thank you so much
