Adaptivity with Simplex Elements in EUROPLEXUS
This report is a sequel to reports and publications [1-12] on mesh adaptivity in fast transient dynamics and presents the formulation and implementation of mesh adaptivity for simplex elements (triangles in 2D, tetrahedra in 3D) in fast transient dynamics. The algorithms are implemented in the EUROPLEXUS code.
EUROPLEXUS [13] is a computer code for fast explicit transient dynamic analysis of fluid-structure systems jointly developed by the French Commissariat à l’Energie Atomique et aux Energies Alternatives (CEA Saclay) and by the Joint Research Centre of the European Commission (JRC Ispra).
The present work extends mesh adaptivity to simplex element shapes, i.e. the 3-node triangle (TRI3) in 2D and the 4-node tetrahedron (TET4) in 3D. These elements are useful in fully general unstructured meshing of complex geometries.
