Hi,

I'm wondering of the exact definition of some variable calculators provided by CFX POST, such as (Velocity u.Gradient X), (Velocity v.Gradient Y), (Velocity w.Gradient Z) please?

Do they simply mean the velocity component gradient on each direction please?　In that case, the value should have a unit of "s", however, I noticed there is not such unit. Besides, I sum the above three terms in order to verify the conservation of mass (density is constant), while the result is far from zero (in solve process, the calculation reached convergency). Similar thing also happens when I　tried to check momentum equation balance.

Could anyone give me advice or help please？

Thanks!
