CFX arcmodeling, User Fortran, CEL....
Hello! Can you give me advice, about arcmodeling in CFX!
I want, first of all, use simplest onezonal model, with considering ( at first) only joule heating: diagramm here: http://img300.imageshack.us/my.php?image=pical3.png Algorithm is: 1)Computing temperature field by given temperature distribution on electrode surface. 2)Computing source energy terms in each arc point, by User Fortran procedures 3)Next iteration The biggest problem it's step 2)! Which functions of USer Fortran or CEL should I use for calculating E(z)=i(t)/[2π∫σ(r,z,t)rdr], where σ(T)=σTT(x,y,z,t)n, T  temperature ? Thanks!!!

For step 2) I need use CFX USER_GETVAR function? Where I can find examples of using this function?

Re: CFX arcmodeling, User Fortran, CEL....
I think, I should use some of Data Acquisition Routines For exmaple USER_GETVAR function...
But, my algorithm used integration... I need integrate temperature by specific location ( by arc section areas ) ... And this location depend from mesh density and there not defined as <LOCATION> in CFX ( and have not CFX locator, and I can't use AreaInt functions )... Can you tell me, how realize the most simple integration in User Fortran! Thanks CFXers!
