Using Mixed Robin Boundary Conditions in FEATool
Using Mixed Robin Boundary Conditions in FEATool
Robin boundary conditions or mixed Dirichlet (prescribed value) and Neumann (flux) conditions are a third type of boundary condition that for example can be used to implement convective heat transfer and electromagnetic impedance boundary conditions. In the following it will be discussed how mixed Robin conditions are …
Periodic Boundary Conditions and the Solver Hook Functionality
Periodic Boundary Conditions and the Solver Hook Functionality
This post describes how to implement finite element FEM models with custom periodic boundary conditions in FEATool. A periodic boundary condition can be defined for opposing boundaries so that their values are linked in some defined way. The typical case for two periodic boundaries is to require them to have identical …
