how to calculate mixed derivative
Dear Foamers,
Is there any way to compute second order mixed derivatives ?
But different than using twice grad operator ?
Thanks !

e.g.
could mixed derivative as:
be calculated using fvc::laplacian method, as follows:
HTML Code:
nu = (0 1 0 0 0 0 0 0 0 );
fvc::laplacian(nu,f)
??
It does something, but I am not sure what ...
Thanks
