An explicit filtering technique is applied to the shape derivatives in order to extract noise from the mesh-based representation of high-resolution. In a CAD-free optimisation strategy the method is applied to a semi-circular profile in incompressible, external flow. It was observed that the filtering is particularly relevant at high Reynolds-numbers. In the complex scenario of ship hull design, the filtered shape derivative can directly be applied to the base-line configuration in order to support both manual and automatic shape optimisation.en0045-7930201112232Elsevier ScienceAdjoint ransDesign optimizationFiltered shape derivativesGradient smoothnessUnstructured gridsTechnikJournal Article10.1016/j.compfluid.2011.01.041Other
