Adaptive unstructured grid for two-dimensional Euler equations
Chang Li · Journal of Propulsion Technology · 2002
An approach for generating adaptive unstructured grid was developed to solve the two dimensional Euler equations. The internal point position was computed according to the size parameter prescribed by the background grid. It was then introduced into the existing grid utilizing Delaunay criterion. The related algorithm is of great simplicity allowance for automatic and flexible treatment of arbitrary shapes and flow features.
