Default Calculation of Gradients

Posts: n/a
Hallo everybody

I have calcualted some gradients using the operate->multi registre->gradient

I reg 1, 2 and 3 the gradients of the u, v and w velocity is stored. Performing the gradient-operation gives me the grdx, grdy and grdz.

Now my questions are: 1) are these the gradients of the velocities stored in the registres before performing gradient?? (du/dx, dv/dy and dw/dz

2) What are the dimension of these?? 1/s or if I have made the model in mm 1000 * 1/s (1 m/s / x mm where x is the distance between two vertices)???
