Addressing More Difficult Problems
If heat flow on a square were all we wanted to do, then there would probably be no need for FlexPDE. The power of the FlexPDE system comes from the fact that almost any functional form may be specified for the material parameters, the equation terms, or the output functions. The geometries may be enormously complex, and the output specification is concise and powerful.
In the following sections, we will address some of the common situations that arise in real problems, and show how they may be treated in FlexPDE.
