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.

NairnFEA does only 2D, linear elastic and 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
• Meshes from images and shapes
• True periodic boundary conditions
• Several options for modeling cracks and doing fracture mechanics calculations
• Can model imperfect interfaces in composite materials
• Residual Stresses
