Open source finite element analysis program.

The objective is to develop a robust structural analysis tool, which is owned by the community, and allows the users to improve and adapt it for their own needs.

It's all about developing tools that allow us to keep going forward (much in the sense of designing for strength, economy and beauty) instead of repeating the same old solutions but in a faster way.

The program is based on:

• Python.
• OpenSees.
• Visualization ToolKit (VTK).
• Boost c++ libraries.
• Computational geometry algorithms library (CGAL).
• NumPy.
• SciPy.
• LaTeX.
• Matplotlib.
• libmpfr. Multiple precision floating-point computation developers tools (libmpfr).
• libgmp. Multiple precision arithmetic library developers tools (libgmp).
• libmysql++. MySQL C++ library bindings.
• Berkeley DB. Berkeley database libraries for C++ (libdb,libdb-dev).
• SQLite 3 development files (libsqlite3).
• Arpack (Fortran77 subroutines to solve large scale eigenvalue problems; libarcpack2-dev).
• Arpack++ (object-oriented version of the ARPACK package).
• Lapack Library of linear algebra routines; (liblapack-dev).
• SuperLU (Direct solution of large, sparse systems of linear equations libsuperlu3-dev).
• Suitesparse (collection of libraries for computations for sparse matrices).
• PETSC (Portable, Extensible Toolkit for Scientific Computation).
• Skypack (SKYline PACKage).
• SuiteSparse (a suite of sparse matrix algorithms).
• ITPACK (collection of subroutines for solving large sparse linear systems by adaptive accelerated iterative algorithms).
• xc_basic Basic routines for XC (that will be simplified...).
• xc_utils Utilities for XC (that will be simplified...).

The main capabilities of the program:

• Geometry modeling and mesh generation tools.
• OD, 1D, 2D and 3D elements.
• Linear and non-linear analysis, static and dynamic.
• Fiber section models (modelization of RC members,...).
• Activation an deactivation of elements (construction phases,...).
• Tools for implementing structural codes (Eurocodes, ACI, AISC,...) verifications (in progress...).
• Interface with Salome (in progress...).
• Interface with SCIA Engineering (in progress...).

You can take a look to the project home, to the Python documentation or the C++ API documentation or to our brand new XC page in the company site. (all of them are work in progress ;-).
