Abstract :
Finite-element solution efficiency and accuracy can be directly affected by mesh quality. When employing h-adaptive solution strategies, a mesh improvement stage is required in order to ensure high-quality tetrahedra. The potential benefits and related costs of a family of new mesh smoothing techniques are investigated with electromagnetic benchmark systems.
