Advances in Pressure-Velocity Coupled Solver

Computational fluid dynamics (CFD) tools are regularly used for complex, coupled and non- linear heat and mass transfer problems. With the development of modern computers and accessibility of High-Performance Computing (HPC) clusters with substantial memory resources, early compromises in the concept of simulation tools can be revisited. The system of equations is usually dominated by inter- equation coupling terms. Most algorithms use conventional segregated approach and solve the equations sequentially. New solution techniques rely on linearisation of inter-equation coupling and solution in an implicit coupled manner. The benefits of the coupled approach are significant reduction in time-to-solution and numerical stability of the algorithm, but at a cost of increased memory usage.
