Thermal solver features

The thermal solver solves steady state and transient heat transfer solutions. The solver is based on a finite element, finite volume formulation. It uses the conjugate gradient algorithm that employs a bi-conjugate gradient stabilized technique, with a pre-conditioning matrix. Because the solver utilizes the Newton-Raphson method for non-linear terms, it provides high performance for large, ill-conditioned systems. The solver also simulates diffuse radiative exchange with automatic view factor calculations for complex enclosures and shadowing surfaces.
