Hello,
How can I calculate the (u_i.j)(u_i,j) term that is needed in the 'rd' parameter of Delayed DES 1 equation turbulence model? Is it similar to dot product like this: (du/dx)*(du/dx) + (du/dy)*(du/dy) + (du/dz)*(du/dz) + (dv/dx)*(dv/dx) + (dv/dy)*dv/dy) + (dv/dz)*(dv/dz) + (dw/dx)*(dw/dx) + (dw/dy)*(dw/dy) + (dw/dz)*(dw/dz)?
Thanks in advance.
