NairnFEA is the open-source code engines engine in this package for doing finite element analysis calculations. It is object-oriented C++ code that can run on many platforms. The main calculations are parallel code. You run calculations by creating Input Files for FEA Calculations. Once the calculations are done, you have a variety of options for 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):
- Plane strain, plain stress, and axisymmetric calculations
- Support multiple types of elements
- Can model both isotropic and anisotropic materials
- Can create a mesh from a digital image
- Can create a mesh with shape commands
- Can model true periodic boundary conditions
- Several options for modeling cracks and doing fracture mechanics calculations
- Can model imperfect interfaces in composite materials
- Can calculate thermal residual stresses
