Vishal Guest Posts: n/a	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
