Welcome to the ABC-library site

A library for Finite Element Computations.

 

ABC-library is a library of C-functions for:

 

  1. Finite element computations: Finite element solvers for elliptic and parabolic problems, finite element grids, and finite element basis functions.
  2. Solvers for systems of linear equations: Standard direct and iterative solvers
  3. Functions for reading input: Text-input using macros, if-then-else-tests, variables and calculations.

 

Abc-lib is a library of C-functions for building finite element applications. The library has Finite Element (FE) solvers for elliptic and parabolic problems in 1- 2- or 3-dimensions with flexible boundary conditions. These FE-solvers are based on functions for FE grids, FE basis functions and solvers for linear equation systems. The solvers cover the standard direct and iterative solvers. In addition, Abc-lib comes with functions for reading input, where the input may apply macros, if-then-else-tests, numerical calculations and variables. Finally, there are also functions for storing the results in a machine/platform independent way. Some simple applications are included for demonstration and testing, along with documentation.

See examples of graphics output here.

Abc-lib does not include any tools for graphics or for making graphical user interfaces, (GUI's). Users of the library are suggested to take a look at Tcl/Tk for interface building and VTK for building visualization tools.

The library is distributed under the GNU General Public License.

Notice that the library comes with no warranty, see the GNU license, and be aware that both the library and the documentation are under development. Abc-lib was formerly known as MLib.
