Comsol Multiphysics/Script - Heat transfer problem

  1. Apr 30, 2008 #1
    Hi everybody

    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.

    Please help!!!
