UDF code for arc as heat flux in simulation

December 23, 2008, 06:41

Hi everybody,

I want to apply an arc equation (Goldak model for arc) as a heat flux in boundary condition and my problem is 3-D simulation of arc welding. please help me to write this UDF code.

I also have the same problem. I wand to apply a cosine equation as heat flux boundary condition for evacuated solar tube.

I need to make welding simulations using the Goldak model but I have a problem with udf. I would like to ask for help

how about your simulation?
please read my paper, Three-dimensional numerical study of heat transfer characteristics of parabolic trough receiver

hey i have a problem in modeling the double ellipsoid model of goldak in ansys coding apdl program does anyone have done the same job and if yes could you send me a text with your code?
I am having my master thesis there is no way of commercializing your work
