Automatic mesh pre-optimization based on the geometric discretization error
The design process usually implies modifications of an initial design solution. At this point in time, design tools do not allow us to perform these modifications efficiently enough. Particularly, when using FE methods a new FE model has to be rebuilt in order to take into account any modification of the geometric model. We propose an original approach that allows the automatic remeshing of 3D parts, which provides a better integration of FE methods into the whole CAD/CAM process. Optimization of automatic remeshing is achieved through mesh pre-optimization based on the discretization error. This introduces, in the FE analysis process, a mesh that represents a better approximation of the exact geometric model. This paper deals with the concept of mesh pre-optimization.
