Abstract
Two methods for mesh modification are considered to improve hybrid meshes for CFD calculations. The first method is an adaptation with new sensors. The new sensors are based on an adjoint approach to calculate the sensitivity with respect to a goal function. Here the sensitivity of lift, drag and pitching moment was calculated with respect to the numerical dissipation terms. The second method is a local mesh modification of the unstructured part of the hybrid mesh based on an algebraic quality measure. For an a posteriori improvement the flow properties can be included to build a new anisotropic metric. Both new methods were applied to industrial relevant test cases.
