Package modulef-99-8

Modulef has been used for many years in the teaching of finite element methods, but also in serious computations in research laboratories. From the web site: The following capabilities are available in the MODULEF library: Automatic generation and modification of two- and three-dimensional meshes. Specification of material characteristics or external forces by sub-domain or boundary section. Choice of type of finite element method, for example, conforming, non-conforming, hybrid, or mixed. For non-conforming methods the flow and stresses can be computed along with the temperature or displacement, or separately. The finite element library contains about 36 elements for thermal analysis and about 61 elements for elasticity for isotropic and anisotropic materials and 4 elements for magnetism and 2 elements for piezoelectric materials. Linear systems can be solved using direct or iterative methods. Solution methods for eigenproblems include inverse iteration, subspace iteration, Lanczos and QR methods. Solution of time-dependent thermal problems and dynamic problems; variational inequalities; Solution of the Dirichlet problem for a biharmonic operator by a mixed finite element method of order 1 or 2. Calculation of velocities and pressure of a viscous incompressible fluid (Navier-Stokes equations). Computation of homogenised coefficients of composite structures. Decomposition of domains. Several modules are available for the display of results, interactively or in batch, for example to plot two- or three-dimensional meshes, deformations, stresses, isovalues, velocities and streamlines in fluid mechanics, etc.

There is an extensive on-line documentation at http://www-rocq.inria.fr/modulef/Doc/GB/welcome.html If you want to browse this documentation locally (in English and in French), install the modulefdoc package. Before starting to work with Modulef, run the command setup_modulef in the shell from which you will be working.
