An element-based three-dimensional CFD code independent of grid structures
A model called CFSV model and a system for three-dimensional fluid analysis constructed on this model are introduced. The model regards generally every equation for numerical analysis as a relation among elements such as cell, face side and vertex. In this model, concepts of category and connection are introduced. Category is a combination of the type of an element and its position in the domain of analysis, and led to loop procedures commonly usable in any part of the computer code. Connection is a combination of the type of two elements, and is considered to unify the method to acquire the sequential number of the neighboring element to an element. The model and the system can be used independent of numerical methods and grid structures. They can decrease the loads while producing, improving and managing computer codes.
