E term in Launder and Sharma (1974) Model
 
Hi
I want write a udf for Launder and Sharma in FLUENT. (I Don't want to use inbuilt model of FLUENT). However, I am not able to write the source term E in the dissipation equation. The E term is represented as,
E = 2ννt*(∂2Ui/∂xj∂xk)2

Could you please explain how do i write this term for 3D Cartesian geometries.
Your help would be highly appreciated.
