Hello! I am trying to write a UDF for fluent. I want to calculate the gradient of a tension. I want to calculate ∂τ/∂x for a source term that adds to energy equation. Does anybody have any idea how can I do that. Thank you

There is nothing for tension. You should calculate if from velocity gradiant. You can find it in fluent manual. C_U_G(c,t)[0], C_U_G(c,t)[1], C_U_G(c,t)[2]
