freefem3d | A language and solver for partial differential equations in 3D | Mehr ...
FreeFEM3D (aka ff3d) is a 3D solver of partial differential equations (PDE). It is a member of the familly of the freefem programs (see http://www.freefem.org). . ff3d, as well as its cousins, is a PDE solver driven by a user-friendly language. It solves many kind of problems such as elasticity, fluids (Stokes and Navier-Stokes) and a lot more. The user has to enter the equation associated with the problem, giving either the PDE in strong formulation or weak (variational) formulation. . ff3d can use either the Finite Elements method (the mesh of the geometry being provided by the user) or a Fictitious Domain like approach where the geometry is described using Constructive Solid Geometry (CSG). This description is done using the POV-Ray language but others such as VRML could be added. . The processing of the results is left to the user. One can use various graphic tools: output in the MEdit mesh format or VTK are supported. The implementation of a VTK base visualization module is underway. . The goal of ff3d is to provide a good teaching tool and a research toolbox (the code is written in C++ and its design is such that new methods can be easily implemented).
