Dear SfePy Users,
I want to solve a thermal problem with the following issues
- several separated regions (bodies) that
- exchange heat via radiation and
- have anisotropic, temperature dependend material properties.
The core of this problem is that the boundary conditions (heat flux given by radiation) are non-local, i.e. they depend on the dependent variable (temperature) of other boundary regions.
How do you plan to resolve the nonlinearity?
Can I solve this kind of problem with SfePy?
IMO the necessary ingredients to create the matrices, integrate the heat flux etc. are (*) available, but you would need to build the complete problem, including the nonlinear iteration, yourself.
Best regards, r.
(*) I have no experience with radiation heat flux, so take this with the grain of salt.
Thanks for input Michael
