Pamgen swMATH ID: 16720 Software Authors: Hensinger, D.M., Drake, R.R., Foucar, J.G., Gardiner, T.A. Description: Pamgen, a library for parallel generation of simple finite element meshes. Generating finite-element meshes is a serious bottleneck for large parallel simulations. When mesh generation is limited to serial machines and element counts approach a billion, this bottleneck becomes a roadblock. pamgen is a parallel mesh generation library that allows on-the-fly scalable generation of hexahedral and quadrilateral finite element meshes for several simple geometries. It has been used to generate more that 1.1 billion elements on 17,576 processors. pamgen generates an unstructured finite element mesh on each processor at the start of a simulation. The mesh is specified by commands passed to the library as a ”C”-programming language string. The resulting mesh geometry, topology, and communication information can then be queried through an API. pamgen allows specification of boundary condition application regions using sidesets (element faces) and nodesets (collections of nodes). It supports several simple geometry types. It has multiple alternatives for mesh grading. It has several alternatives for the initial domain decompositon. pamgen makes it easy to change details of the finite element mesh and is very usesful for performance studies and scoping calculations.
