Development of numerical algorithms for end-user applications in aerospace

In this paper, a cross-section of numerical algorithm development at NLR for end-user applications in aerospace is presented. Aerospace is characterized by high safety requirements and standards, complex development programs and operational processes, and challenging multi-physics phenomena. An example is the certification or qualification of...

A Simple, Robust and Fast Algorithm to Compute Deformations of Multi-Block Structured Grids

A grid deformation method has been developed for the movement of multiblock, structured grids due to surface deformation arising from aeroelastics or design optimisation. The method uses a volume spline interpolation technique to compute the deformation of block vertices and block edges. After that, the deformation of block-faces is computed by...
