  KEYWORD

Study and implementation of orthogonal polynomial bases on polygonal or polyhedral elements for the discretization of PDE with virtual elements

keywords GALERKIN METHODS, VIRTUAL ELEMENT METHOD

Reference persons STEFANO BERRONE, ANDREA BORIO

Research Groups Analisi numerica e calcolo scientifico

Description When considering elements with large aspect ratios or sides with very different dimensions, the use of the monomial bases for the implementation of VEM elements results to show instability due to numerical conditioning problems. In these cases alternative poinomial bases have been developed which show good robustness properties.

Required skills Good knowledge of both theoretical and implementation FEM methods
