IGAFrac is a MATLAB code for simulating fracture within the Iso-Geometric Analysis paradigm. The geometry is represented by PHT-splines (polynomial splines over hierarchical T-meshes), and is based on the nurbs package (distributed under the GNU General Public License v3.0). The code adopts a modular style, similar to that of PyFEM.
The following models are available:
- Linear Elasticity
- Phase-field Fracture
- Isotropic Elastic
- Newton-Raphson
- Staggered
- Quasi Newton-Raphson with extrapolation
- Arc-length
- Realtime output
- VTK writer
- Run one of the examples in 'inputData' folder!
