How to access or generate double derivatives?

Hi, Can somebody please tell me how to access or specify (at the boundary) second order derivatives of velocity components, concentration in Fluent? Is it ok to define a UDS equal to first order derivative and then store the the gradient of this UDS in some UDM? Will this method work? Or is there any other way out? Thanks & Regards, Vishal

Search this forum for "second derivative" and you could find a lot of discussions about this. Someone suggested that you could use finite difference formula to calculate these derivatives. Good luck!
