Boundary Conditions
There are three types of boundary conditions commonly encountered in the solution of partial differential equations:
1. Dirichlet boundary conditions specify the value of the function on a surface 
.
2. Neumann boundary conditions specify the normal derivative of the function on a surface,
 |
3. Robin boundary conditions. For an elliptic partial differential equation in a region 
, Robin boundary
conditions specify the sum of 
and the normal
derivative of 
at all points of the boundary of 
, with 
and 
being prescribed.
