Two coordinate systems in one region
 

I want to define radial BC profiles at two differently oriented boundaries of one region. The only setting I found to have an effect on the region COS is under physics values -> axis, defining the proper COS there. Obviously that method allows to define ONE custom COS per region, so as of now only one radial profile at a time works. Steady model.



Is there any other way to define that, two regions is not an option, the internal interface boundary is horrible.


Thanks,

That response is crap, but I am hoping someone might still have a helpful suggestion.

We want to avoid using a (signal),x,y,z profile for the second boundary and define that relative to the first boundary with proper local COS applied.


Thanks

Why don't you split the boundary in two and specify the boundary condition for each using independent coordinate systems?

Yes, it is two individual boundaries. What should I set the reference frames to? Do I get the second COS by rotating the first custom one? As I was saying I am aware of those functions but they have not worked for me, whatever I specify there is being overwritten by the physics -> axis section which is valid for the entire region. If you could tell me the exact settings to get that working will be great help.

Thank you !
