Boundary condition problem

[pradeepburla]

Hi Guys,

I hav a block of cube and on the top of the surface I prescribe some concentration.After a while the concentration on the top surface should reduce as some part of the concentration has gone down inside the cube.This is similar to saying I heat the top surface of the cube to 100 degrees centigrade and remove the heat source.Now I want to see the heat distribution inside the cube.Even the temperature of the top surface should come down as there is no source term.
I am not sure how I can acheive such a simulation.
Any headstart would be of great help.
Thanks.

This can be done with a UAMP. Based on current results you can modify loads.
