Questions for the heat equation

Please login with a confirmed email address before reporting spam

Hi All,
I’m considering two 2-dimentional regions, non-geometrically related to each other. I’m trying to solve a steady-state equation of convective heat. For the first region I’m setting the temperature and the flux on the left boundary and a convective flux on the right boundary and getting the temperature on the right boundary. Now the question is how is it possible to substitute this distribution as a boundary condition for the SECOND region in the form of T(x,y). Are these values stored in a variable of some sort?
I have another question.
I’m trying to solve an unsteady heat equation in time. I want to get the values of the flux at a certain boundary (boundary integration) and in the time-varying subdomain (subdomain integration). Is it possible to output them to a file with a specified time scale?
