www.math.uci.edu1.2. Boundarycondition. We use bdFlag(1:NT,1:d+1)to record the type of boundary sides (edges in 2-D and faces in 3-D). The value is the type of boundary condition: 0 for non-boundary sides; 1 for the first type, i.e., Dirichlet boundary; 2 for the second type, i.e., Neumann boundary; 3 for the third type, i.e., Robin boundary. 1
2.4 Mixed or Robin Boundary Conditions
ksuweb.kennesaw.edu2.4 Mixed or Robin Boundary Conditions 2.4.1 Goal Learn how to solve a IBVP with homogeneous mixed boundary conditions and in the process, learn how to handle eigenvalues when they do not have a ™nice™ formula. 2.4.2 An example with Mixed Boundary Conditions The examples we did in the previous section with Dirichlet, Neumann, or pe-

ramanujan.math.trinity.eduNeumann Boundary Conditions Robin Boundary Conditions Remarks At any given time, the average temperature in the bar is u(t) = 1 L Z L 0 u(x,t)dx. In the case of Neumann boundary conditions, one has u(t) = a 0 = f. That is, the average temperature is constant and is equal to the initial average temperature.
