NairnFEA

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
