Difference Funtions

Postby haslim1554 » Fri Jan 29, 2016 11:00 pm


i just need to confirm this difference functions i using here. I need to find the vorticity in x direction, in doing that i need to find the difference of differential vertical velocity(W) to y-axis and differential lateral velocity (V) to z-axis. Is this the correct way to write the function,

streamwise vorticity (Vnew) = ddy(W) - ddz(V).


Best Regards
