WebA final remark should be made regarding the computational time. For the fixed cylinder and the case with a oscillation frequency f c = 0.16, the simulations with the morphing mesh are much faster. For increasing frequency however, the maximum Courant number Co max had to be decreased from 0.75 for f c = 0.16 to Co max = 0.5 for f c = 0.3 and Co max = 0.25 … Web12 okt. 2024 · A mesh morphing method has been developed and embedded into an hydrodynamic design by optimization process to reduce the overall computational effort …
