Gradient of a Custom Field Function -- CFD Online Discussion Forums

December 11, 2019, 12:49	Gradient of a Custom Field Function	#1
PierceH Member Pierce Join Date: May 2019 Posts: 39 Rep Power: 6	Hello, I'm new to Fluent and I want to calculate the gradient of a custom field function which I can then input as a source term to a user defined scalar where I will take the divergence of the term I've just calculated the gradient for (along with an additional cross product term). Unlike in STAR CCM+ it appears that there is no vector calculus options and i'm unsure how to proceed.
