High-order mesh curving by distortion minimization with boundary nodes free to slide on a 3D CAD representation ?
We present a method to generate curved high-order meshes for industrial applications. The method is based on the minimization of a single and global objective function. The objective function is defined as the distortion of the volume mesh. To enlarge the feasible region, boundary nodes are free to slide on the CAD model. A block iterative implementation of the global objective function is presented.
