Temperature results node by node

Jared1986 · December 7, 2016, 08:55

Hello to everybody, I have question concern to calculating and setting boundary conditions directly to each node for separate domain. I'd like to know If it is possible to set and change boundary condition for each mesh element based on temperature measured on that element? Thanks a lot for answer...

There's no such built-in functionality. You should utilize User Fortran.

Maybe I'm misunderstanding something, but it seems you could do this by just making the boundary condition a function of temperature. It will then be applied to each node based on local temperature.

For example,
Create and expression: HeatGen = (HeatGenFunction*Temperature)[W/m^3/K]
Or a user function where you have a table of temperature and boundary values.
Then insert that in as a source or subdomain: MyHeatGenFunction(T)
