Abstract
A general and efficient remeshing algorithm is presented for the discretization of arbitrary planar domains into triangular elements in consistency with the given node spacing function.The contour lines of the node spacing function at suitable calculated levels provide the natural lines of division of the problem domain into subregions, where finite element meshes of different element sizes are generated using the available general‐purpose mesh generators.1, 2Examples of remeshing for various node spacing functions are given to illustrate that high‐quality gradation meshes can be generated automatically without any user's intervention by this simple contour line method.Keywords
