Abstract
OOF2 is public domain finite element analysis software created at the National Institute of Standards and Technology (NIST) to investigate the properties of microstructures. At the simplest level, OOF2 is designed to understand the effects of far fields (boundary conditions) on the local microstructural fields, or to assess the mechanical, electrical, and thermal reliability of a material with a complex topology. OOF2 allows the user to study the thermal, electrical, and stress fields in a microstructure, along with couplings such as piezoelectricity, pyroelectricity, and thermal expansion. OOF2 can also perform crystallographic analyses of polycrystalline materials by using tensor form material properties. The inputs necessary to perform a simulation include: 1) a microstructure (real micrograph or computer generated), 2) material properties and 3) boundary conditions. The specified information enables OOF2 to simulate the multiphysical properties, thus allowing to analyze and engineer the effect of microstructure. The figures below show 1) the input image, a lamellar directionally solidified eutectic of NiO and yttria-stabilized ZrO2, 2) a zoomed in view of the mesh, and 3) the stresses developed in the microstructure due to an temperature increase.
NOTE: Version 2.3.0 introduces some major changes. Please see the OOF2 change log for the details. In particular, some of the Skeleton modification tools have changed. Please contact the OOF2 developers if you need assistance converting scripts to the new format.
You can still run OOF2 2.2.3 if you encounter difficulties with 2.3.0.
