Optimizing the geometrical accuracy of curvilinear meshes [PDF]
Journal of Computational Physics, 2016 This paper presents a method to generate valid high order meshes with optimized geometrical accuracy. The high order meshing procedure starts with a linear mesh, that is subsequently curved without taking care of the validity of the high order elements.
