| Abstract: | The unstructured triangular mesh can be well adapted to complex and irregular boundaries. In this paper, a simple and fast mesh generator to create unstructured meshes of arbitrary two-dimensional domain is introduced. MATLAB has been the preferred technical computing language for fast development and simplified design. The mesh generator is well implemented by means of MATLAB with COMSOL Multiphysics. Several hydrodynamics problems are simulated using finite volume method on unstructured grid to verify its... |
