WebThe Coefficient Form Boundary PDE is an interface for lower dimensions (boundaries) and is based on the finite element method, whereas the PDE, Boundary Elements interface is based on the boundary element method and is not available for lower-dimensional equations. The Coefficient Form Boundary PDE WebFor the Coefficient Form PDE, there are two important boundary conditions. The first is the generalized Neumann boundary condition: , which is used to model a boundary flux. The second is the Dirichlet boundary condition: which is used to assign fixed values of the dependent variable — in this case the concentration — on the boundary.
