The numerical errors involving the application of the level-set method to a problem can be minimized by fitting a mesh (usually a triangular mesh in two dimensions) to the zero level-set curve defined by the level-set function. These numerical errors depend on two things: the size and skewness of the triangles in the mesh. To fit the mesh, Timo Wortelboer derived a physical model using springs (Wortelboer, 2018). He also defined measures to quantify the quality of a fitted mesh. First, his model is analyzed, as well as the quality measures he defined. Then an introduction on linear isotropic elasticity is given, based on which an elastic model for meshfitting is derived. The Finite Element Method is used to solve the differential equations of the elastic model. Then an optimisation algorithm is introduced to change the Lamé parameters such that the quality of the mesh is improved even more. Lastly the spring model and the elastic model are compared, which results in the elastic model being better than the spring model.
