Boundary conditions (b.c.) are constraints necessary for the solution of a boundary value problem. … Boundary value problems are extremely important as they model a vast amount of phenomena and applications, from solid mechanics to heat transfer, from fluid mechanics to acoustic diffusionA simply-supported beam (or a simple beam , for short), has the following boundary conditions: w(0)=0 . Because the beam is pinned to its support, the beam cannot experience deflection at the left-hand support.
