regarding UDF problem

February 24, 2003, 02:29

hi all I want to know how deal with UDF problem. My project is to solve temperature and velocity field(2D) in EAF(electric arc furnace) I use k-e turbulence model. I would like to add the Lorentz force(source term) at z-axis in momentum equation, and joule heating and Thompson effect(source terms) in energy equation

please! tell me how to write UDF!!

Lorentz force defines Jz*Btheta Jz=2*I/PI*R^4(R^2-r^2)

Btheta=Mu*I*(r/R^2-r^3/2*R^4)

Government Equation add this source term.

So I want to konw how to write UDF forms
