WebJan 1, 1997 · In other words, the PDE is only solved on the domain z ∈ [0; ℓ(t)] at every time t. This makes the problem a so-called moving boundary problem, which essentially denotes a differential problem ... WebOct 25, 2024 · The book presents in comprehensive detail numerical solutions to boundary value problems of a number of non-linear differential equations. Replacing derivatives by finite difference approximations in these differential equations leads to a system of non-linear algebraic equations which we have solved using Newton’s iterative method.
