ViennaMaterials - A dedicated material library for computational science and engineering

The design and implementation aspects of the dedicated C++ materials library ViennaMaterials for science and engineering is discussed. The library's focus is to provide flexible application programming interfaces for accessing material data. Special attention is on handling physical units as well as supporting mathematical material models via a nested code evaluation mechanism. The challenges of supporting different programming languages, physical units, mathematical models, and a run-time setting are tackled by utilizing external tools on top of a flexible object-oriented library structure. Application examples covering the utilization with a numerical simulation as well as a remote network-based material database are discussed to underline the usability of ViennaMaterials.
