Sažetak
An overview is presented about the relative performance of different mesh motion algorithms within the OpenFOAMframework. The new RBF mesh motion is compared with two currently available methods: 1) Solving the Laplacian of mesh velocity field, 2) Solving the solid body rotation stress equations for the mesh displacement field. It will be shown that the RBF method leads to superior mesh motion in terms of mesh quality, especially in cases with large rotations. However, as this RBF mesh motion is rather computationally expensive, methods to improve efficiency will be considered. Additionally, the lift of a flapping wing will be used to investigate the accuracy of the flow solver using all three mesh motion solvers.
