'''NairnFEA''' is the open-source code engines engine in this package for doing finite element analysis calculations. It is object-oriented <tt>C++</tt> code that can run on many platforms. The main calculations are parallel code. You run calculations by creating [[FEA Input Files|Input Files for FEA Calculations]]. Once the calculations are done, you have a variety of options for [[Main Page#Visualization|visualizing and analyzing]] the output.

'''NairnFEA''' does only 2D, linear elastic, static finite element analysis. Some of its features are (click each link for details):

* [[Analysis Command|Plane strain, plain stress, and axisymmetric calculations]]
* [[FEA Elements|Support multiple types of elements]]
* [[FEA Material Models|Can model both isotropic and anisotropic materials]]
* [[Create a Mesh with Images and Shapes|Can create a mesh from a digital image]]
* [[Create a Mesh with Images and Shapes|Can create a mesh with shape commands]]
* [[FEA Periodic Boundaries|Can model true periodic boundary conditions]]
* [[Explicit FEA Cracks|Several options for modeling cracks and doing fracture mechanics calculations]]
* [[Imperfect Interfaces|Can model imperfect interfaces in composite materials]]
