Dear colleagues,
A few days ago, I received the following exercise (my teacher just took a sheet of paper and drawing in the moment without further explanation), but I've never studied thermodynamics before and I don't know very well where to start, the exercise is heat transfer and the use of the method of finite differences, and should I program it in C ++ using PetSc.
The Method of Finite Difference (FDM) for 2D and the equation of Laplace of the I've used previously and I do not have problems to understand it, but I have a few ideas about this topic. I have read and seen many tutorials on YouTube on the subject, but most of them are of a layer, 2D and different temperatures around. However, in this exercise, I have 3 different metals and is in 3D.
I would like to get some recommendations or tips on what I should do or where to read. Thank you for your valuable help, I feel, because I don't have any equation, or relevant information, but my knowledge of this is minimal.
The statement of the problem would be more or less like this:
To obtain the graph of the heat transfer in the following figure, using the finite difference method using PetSc and C ++:
The ambient temperature is 0 degrees celsius.
Thermal conductivity:
