چکیده
Introduction There is a revolution going on, impacting and transforming how computational mechanics and the associated design and optimization are done: the emergence, availability, and large-scale use of OpenFOAM [1]. It belongs to the contemporary open-source trend not unlike the roles played by the Linux operating system or the Internet encyclopedia Wikipedia. OpenFOAM is free and is used by thousands of people worldwide in both academic and industrial settings. The acronym OpenFOAM stands for Open Source Field Operation and Manipulation. Computational mathematics and mechanics provide fundamental methods and tools for simulating physical processes. Numerical computation can offer important insights and data that are either

A General Sparse Sparse Linear System Solver and Its Application in OpenFOAM
Solution of large sparse linear systems is frequently the most time consuming operation in computational fluid dynamics simulations. Improving the scalability of this operation is likely to have significant impact on the overall scalability of application. In this white paper we show scalability results up to a thousand cores for a new algorithm devised to solve large sparse linear systems. We ...
متن کاملNumerical simulation of the fluid dynamics in a 3D spherical model of partially liquefied vitreous due to eye movements under planar interface conditions
Partially liquefied vitreous humor is a common physical and biochemical degenerative change in vitreous body which the liquid component gets separated from collagen fiber network and leads to form a region of liquefaction. The main objective of this research is to investigate how the oscillatory motions influence flow dynamics of partial vitreous liquefaction (PVL). So far computational fluid d...
