Hi, I am working on a 2-D thermal modeling problem for a rectangular region. It is a simple conduction heat equation(elliptic) and I am solving using the pdetool. Except for the top surface other 3 boundaries follow neumann boundary conditions. For the top surface the values are constant , non zero and vary with every point. But the values don't follow any curve either, they are random values. When I initialize mesh, it assigns some nodal points on the top surface and I wish to assign numerical values to these nodal points. Can anyone please tell me how do I do that?
MATLAB: Can I assign values at nodal points for boundary condition
