Comsol Multiphysics/Script - Heat transfer problem
I'm a new user of Comsol Multiphysics and Comsol script. And I'm working on a conduction problem, with convective and radiative heat flux at one boundary. The geometry is quite simple: 2D rectangle. But the upper boundary is supposed to be moving with time (linear or exponential law)
How do I set a heat flux boundary condition on this boundary and specify at the same time that the boundary is moving???
Can I do it on the Multiphysics interface or should I do it through the script (how?) ?
I tried to modify the "geometry field" in the script by setting a rectangle with a dimension moving with time, but I get an error when I try to solve.

In ComSol, how can I impose a condition of the jump of the temperature ([T] = Tu - Td) at the interface between two subdomains in the heat conduction problem?
Thank you in advance.

I have a problem with Comsol: I'm using the heat transfer application mode- conduction and convection in 2D axial simmetry.I need to impose an heat flux of a certain value in a simple subdomain, a rectangle. Comsol let me impose heat transfer only on boundaries, but not inside a subdomain, how can I do?
Please help! Thank you in advance
