GradH-Correction: guaranteed sizing gradation in multi-patch parametric surface meshing

In this paper a new method, called GradH-Correction, for the generation of multi-patch parametric surface meshes with controlled sizing gradation is presented. Such gradation is obtained performing a correction on the size values located on the vertices of the background mesh used to define the control space that governs the meshing process. Numerical results show that meshes generated from corrected control spaces are of high quality and good gradation also when the background mesh has poor quality.
