Dear All,

I am trying to implement a SGS model in openFOAM for incompressible flows. For that i am using existing constant Smagorinsky model implementation.

For my SGS model, I need to access cell velocity components and gradU components.

Can anybody help me out how can i access these components.


Thanks and Regards,
vivek

Hello vivek, do you already solve this problem?

I also meet this problem, thank you!

U_.component(direction)


I also think calling .x(), .y(), .z() should work.



This should work for both since grad() also returns a vectorField.

Thank you sir, I already use the U_.component(0), U_.component(1), to get the Ux, Uy, and so on.

Thanks for your reply!
