Abstract
A method, system and computer program product pertained to adaptive discretization refinement of shell structure is disclosed. The adaptive mesh-free model is based on a technique for dividing the critical area into a finer model. The present invention is a method for enabling adaptive mesh-free shell structure in a time-domain analysis, the method comprises: defining the mesh-free shell structure by a structural geometry description file including a plurality of nodes and a reference 3-D mesh, which includes a plurality of shell elements, mapping the 3-D reference mesh into a 2-D parametric plane, wherein the 2-D parametric mesh includes a plurality of integration cells corresponding to the plurality of shell elements, solving structural responses at current solution cycle using mesh-free mathematical approximations pertaining to each of the plurality of integration cells, performing adaptive discretization refinement for the plurality of the integration cells.
