I think I've a solution using the UDSI !!

I need only the derivatives: Duv/dy and DuČ/dy, uv and vČ are the reynolds stresses. I would like to use them in the DPM_define_bodyforce function, here is a solution, but I am not sure that it will be working: real DuvDy, DvvDy; C_UDSI(c,t,0) = C_RUV(c,t); C_UDSI(c,t,1) = C_RVV(c,t);

DuvDy = C_UDSI_G(c,t,0) [1]; DvvDy = C_UDSI_G(c,t,1) [1];

and deselcting for solving equations for UDS0 and UDS1!!

What do you think about ?

It works, So you know now how you can calculate the Reynolds stress or any scalar Derivatives.

Don(t forget to deselect for solving transport equation for the UDS !!
