Finite element method for 2D planar linear elastic problem Here is the simple code for FEM. The features are following: 1. Linear elastic material 2. Both 4 node and 8 node isoparametric rectangular element is implemented 3. Accept displacement and force boundary condition. Usage: 1. For new FEM learner to understand the implementation. 2. Two input file is given. Only data output is given. Users should find post-processor for themselves. 3. See the comment in the code for details.
