Adaptive mesh generation by bubble packing method
Jeong-Hun Kim, Hyun-Gyu Kim, Byung-Chai Lee and Seyoung Im

    The bubble packing method is implemented for adaptive mesh generation in two and three dimensions. Bubbles on the boundary of a three-dimensional domain are controlled independently of the interior bubbles in the domain, and a modified octree technique is employed to place initial bubbles in the three-dimensional zone. Numerical comparisons are made with other mesh generation techniques to demonstrate the effectiveness of the present bubble packing scheme for two- and three-dimensional domains. It is shown that this bubble packing method provides a high quality of mesh and affordable control of mesh density as well.
Key Words
     mesh generation; bubble packing method; modified octree; error estimator; mesh density function.
