Wall BC in Fluent

a00884062 · August 30, 2009, 02:12

Hi.

Is it possible to set a wall boundary condition in which the temperature of the wall is changing with time (or in other words, can the temperature be updated with every iteration?). I also do not know the heat flux.

I am trying to solve a problem where I have a coil filled with Liquid Nitrogen and I am trying to find the temperature in the center of the coil.
Any ideas or suggestions?

refer to the fluent document, udf help. read the material related to the DEFINE_PROFILE. you can easily find it in its index. you can't change the temperature in each iteration but you can define a fuction for temperature which changes with time. you may find the same codes in its examples.
