Question on Face Temperature Gradient

Hello
I'm a Phd student and I use Fluent software in my Doctor's degree preparation. In my doctoral I do computer modeling and simulation of laser welding and compare this results with experimental cross section of microphotography.In fluent manual, Face Macros haven't temperature gradient vector.I can't add the the _G suffix to access the tempearture gradient something like this -> F_T_G(f,t). Therefoe I'd like to ask how to compute face temperature gradient in UDF.I want to apply this face tempearture gradient to Marangoni phenomenon in specified shear. Bye bye Tomm. |

Hi Tomm,
If you use the F_T_M1 (i think its m1, but check the user guide)this will give you the temperature at the previous time step. You can then calculate the gradient using (change in y value)/(change in x value). ie. in your UDF: gradient = (F_T - F_T_M1)/(timestep size) Hope this helps Mc |
