CFD Mesh Deformation Module

The deformation module "FSDeformation" has been developed for the simulation environment FlowSimulator [1]. It is based on an implementation of the mesh – deformation module presented in [6] using the radial basis function (RBF) inter­polation approach. This approach is extended by the feature of specifying groups of different boundaries with separate interpolation functions and a blending func­tion, which restricts the deformation to a specified zone around these boundaries. Both features are controlled by the distances d of the mesh nodes to the group target boundaries. The distances are calculated by the wall distance module (section 3).

More details about the deformation module, for example concerning parallel per­formance and interpolation quality, can be found in [10].
