the adaptive mesh with the property of boundary-fitted is applied to generate the calculation mesh of the domain of the south of the south china sea.
because the complicated coastlines of the south china sea, the shape of corresponding of calculation domain is also complicated.
generally, it is difficult to fit its boundary with regular mesh.
the application of adaptive mesh coordinates is successful in fitting the boundary lines of calculation domain, which therefore avoids the boundary errors.
due to the complication of the shape of the south china sea, it is not easy to transform one rectangular onto the domain of the south china sea, and its results are not good.
so according to the shape of the south china sea, we designed a region composed of multi - rectangular and transform it onto the domain of the south china sea
