Hi,

Maybe my previous thread wasn't clear enough.

I'm asking how can I access the values of velocity gradients from the previous time step...

Thanks

define a volVectorField V,then use the V.old :
volVectorField magU
(
ioObject(

.........
)
fvc::grad(V),
)

magU.old

may be it works

I have a similar requirement, wondering if C_U_G function can be handled with M1 thing??
