Impact - a Free Explicit Dynamic Finite Element ProgramCrushed profile
Impact is an open source finite element program suite which can be used
to predict most dynamic events such as car crashes or metal sheet punch
operations. They usually involve large deformations and high velocities.
Simulations are made on a virtual three dimensional model which can be
created with a pre-processor or with the built-in Fembic language.
Results are viewed in a post-processor.
Impact is designed to interface with the included pre- and postprocessor
by default, but there are also interfaces available for more advanced
pre-and postprocessors such as GiD or Gmsh. Impact also has rudamentary
support for Nastran file format.
Development is made by a team of volunteers from all over the world with
the aim of creating a clean and compact program which is simple to
understand and use.
Impact is licensed under the Gnu Public License which makes it free to
use and modify as long as you release and publish your improvements
under the same license.
Impact is written in Java which means it can be run on most hardware and
operating systems.

The BRL-CAD package is a powerful Constructive Solid Geometry (CSG)
solid modeling system with over 20 years development and production use
by the U.S. military. BRL-CAD includes an interactive geometry editor,
parallel ray-tracing support for rendering and geometric analysis,
path-tracing for realistic image synthesis, network distributed
framebuffer support, image-processing and signal-processing tools. The
entire package is distributed in source code form.

Open CASCADE Technology, 3D modeling & numerical simulation
Open CASCADE Technology is software development platform freely
available in open source. It includes components for 3D surface and
solid modeling, visualization, data exchange and rapid application
development.
Open CASCADE Technology can be best applied in development of numerical
simulation software including CAD/CAM/CAE, AEC and GIS, as well as PDM
applications.
The Technology exists from the mid 1990-s and has already been used by
numerous commercial clients belonging to different domains − from
software edition to heavy industry.
The platform is provided by the Company bearing the same name − Open
CASCADE S.A. For its clients the Company offers custom development and
technical support services. For more information on the Company please

SALOME is a free software that provides a generic platform for Pre and
Post-Processing for numerical simulation. It is based on an open and
flexible architecture made of reusable components available as free
software.
It is open-source (LGPL), and you can download both the sourcecode and
the executables from this site.
Salome Platform:
* Supports interoperability between CAD modeling and computation
software (CAD-CAE link)
* Makes easier the integration of new components on heterogeneous
systems for numerical computation
* Sets the priority to multi-physics coupling between computation
software
* Provides a generic user interface, user-friendly and efficient,
which helps to reduce the costs and delays of carrying out the studies
* Reduces training time to the specific time for learning the
software solution which has been based on this platform
* All functionalities are accessible through the programmatic
integrated Python console

Elmer - Finite Element Software for Multiphysical Problems
* Elmer is an open-source computational tool for multi-physics
problems. It has been developed in collaboration with Finnish
universities, research laboratories and industry.
* Elmer includes physical models of fluid dynamics, structural
mechanics, electromagnetics and heat transfer. These are described by
partial differential equations which Elmer solves by the Finite Element
Method (FEM).
* Elmer comprises of several different parts: The geometry,
boundary conditions and physical models are defined in ElmerFront. The
resulting problem definition is solved by ElmerSolver. Finally the
results are visualized by ElmerPost. Additionally a utility ElmerGrid
may be used for simple mesh manipulation.
* The different parts of Elmer software may also be used
independently. The strongest of the components is ElmerSolver which
includes many sophisticated features. For pre- and postprosessing the
users may find also other alternatives.
* These pages are intended to give information on the Elmer
software and to improve the information transfer in the Elmer community.

CAELinux
Based on the open-source CAE softwares Salomé & Code_Aster, you can load
STEP / IGES geometry in Salomé and start partitionning and meshing your
problem in just 5 minutes.
Image
Then you can simulate incredibly complexe physics with the ISO 9001
certified FE solver Code_Aster: non-linear thermo-mechanics, coupled
fluid-structure dynamics, sismic / non-linear explicit dynamics,
contacts, visco-plasticity, in other words all that you could imagine
can be simulated with Code_Aster!! Then reload your results files in
Salomé to post-process your data in 3D... And don't forget all these
features are based on open-source / free softwares, so now you don't
have to pay for excessively expensive licenses.
