Adaptatividad Tridimensional con Mallas no Estructuradas

Marcelo J. Vénere, Roberto Saliba, Raúl Feijóo


In this work· some experiences on adaptivity for three dimensional problems are presented. Based on a linear elasticity solver, two different approach for the
discretization changes are ,analysed: subdivision of simplexes and remeshing. With the first one, those elements with an estimated error greater than an acceptable value are divided. With the second, the estimated error is used to define a new element size at the
centre of each element and a new mesh is generated. Both methods are described and some application examples ate presented. Finally the advantage and problems of using these adaptivity techniques are discussed.
