  • An algorithm for mesh refinement and un-refinement in fast transient dynamics 

    Casadei, Folco; Díez, Pedro; Verdugo Rojano, Francesc (2013-08)
    Open Access
    A procedure to locally refine and un-refine an unstructured computational grid of four-node quadrilaterals (in 2D) or of eight-node hexahedra (in 3D) is presented. The chosen refinement strategy generates only elements of ...
