  • High-level generic C++ code for structured and unstructured grid traversal (vertices-on-cell, edges-on-vertex, etc.)
  • Convenient quantity storage and access on grid elements using ViennaData
  • Separates topology of a grid element from the underlying geometric space (e.g. triangular hull meshes in a three-dimensional space)
  • Lines, triangles, quadrilaterals, tetrahedra and hexahedra provided out of the box
  • Allows to write code that works for arbitrary spatial dimensions
  • Targets the requirements of Finite Element and Finite Volume methods
  • Highly customizable internal storage scheme, which allows for highest performance and/or lowest memory footprint for the user's application
