During simulation of blowing of the glass, the mesh has to be adapted due to the extreme deformations of the mesh.
Remeshing Glass forming has not been done that often with a Finite Element Approach (FEM), since the material behavior lies somewhere between a fluid, which is the domain of Computational Fluid Dynamics (CFD) and a solid, which is the domain of FEM.
