Cfd-Geom	Cfd-Geom is a general-purpose geometry and grid generation system with an extensive set of geometry creation and manipulation, CAD import, and mesh generation capabilities. Cfd-Geom provides meshes for solver packages Cfd-Ace+ and Cfd-Fastran. It can also be used with other CFD/FEA/CAE packages. It also supports the scripting language Python.
Cfd-Viscart	Cfd-VisCart is an adaptive cartesian mesh generation system for use with the Cfd-Ace+ and Cfd-Fastran flow solvers. Cfd-VisCart is ideally suited for extremely complex geometries such as underhood for automotive applications and full aircraft configurations for aerospace applications. Significant advantages are its robustness and ease-of-use. It handles imperfect geometries with holes, overlaps and cracks. Furthermore, it offers solution-based adaptive mesh refinement for obtaining optimal mesh resolution.
Femap	FEMAP enables face-based loadings (e.g.,Pressure, Convections, Radiations) applied to geometric surfaces, where the resulting FEA load would be a face-based load on shell elements, to expand from the surface to the associated finite element mesh. This only affects face-based loadings and only when they are applied to a surface that is associated with shell elements.
Gambit	Different CFD problems require different mesh types, and GAMBIT gives you all theoptions you need in a single package. GAMBIT's meshing toolkit lets you decompose geometries for structured hex meshing or perform automated hex meshing with control over clustering. Triangular surface meshes and tetrahedral volume meshes can be created within a single environment, along with pyramids and prisms for hybrid meshing.
Gid	Gid has been designed as a universal, adaptive and user-friendly graphical user interface for geometrical modelling, data input and visualisation of results for all types of numerical simulation programs. Gid is ideal for generating all the information (structured and unstructured meshes, boundary and loading conditions, material types, visualisation of results, etc.) required for the analysis of any problem in science and engineering using numerical methods. Gid is easy to adapt to any numerical simulation code.
GridCAD	GridCAD is a powerful tool for 2D and 3D structured or unstructured grid / mesh generation, steady or unsteady computation of 3D grids, aeroelastic phenomena and CAD modeling.
Griddle	Griddle is a mesh generator designed on the premise that grid generation should be easy, quick and cheap to perform. To this end Griddle requires only such information as is essential in defining the topology and the mesh parameters of a grid. In this sense Griddle is intuitive in that it requires the minimum amount of information, in the same order in which one would intrinsically think about the design of a grid.
Gridgen	Gridgen is being used to prepare geometry data for computer simulations of fluid flow. Gridgen accomplishes this by serving as the enabling software bridge that connects computer aided design (CAD) software and analysis software such as computational fluid dynamics (CFD) and finite element analysis (FEA). The system consists of two codes - interactive Gridgen and batch Gridgen3D. These two codes can create: Quadrilateral and hexahedral grid cells, triangular and tetrahedral grid cells, mapped meshes, hybrid meshes including prisms and pyramids, single or multiple blocks, abutting or overlapping block interfaces, two- and three-dimensional blocks.
GridPro	GridPro is an automatic object oriented multiblock grid generator based upon a powerful topology engine. It provides ease of use, high quality, rapid generation, and modular parametric design. A dynamic 3D graphic environment provides users with an extremely efficient interactive capability to build topology, edit surfaces, set CFD boundary conditions, and to view multiblock grids.
Harpoon	Harpoon is a cartesian mesh genarator for cfd and fea applications. With Harpoon, surface geometry is brought in through STL files. Model surfaces need not be watertight. Harpoon tolerates gaps and overlaps of surface data that would require tedious "cleanup" procedures in most other meshers. Harpoon meshes are hexahedral-dominant. To assure high mesh fidelity near model surfaces, tetrahedra, prism and pyramid cells are employed.
HyperMesh	Altair HyperMesh is a high performance finite element pre and post-processor that enables you to generate finite element and finite difference models for engineering simulation and analysis. HyperMesh provides a variety of data import options to facilitate concurrent engineering, as well as fast model building and advanced post-processing capabilities for in-depth visualization of complex simulations.
Icem CFD	ICEM CFD Engineering markets software for pre- and post-processing of engineering applications such as computational fluid dynamics and structural analysis. The grid generation tools of ICEM CFD offer the capability to create grids from geometry in multi-block structured, unstructured hexahedral, tetrahedral, hybrid grids consisting of hexahedral, tetrahedral, pyramidal and prismatic cells, as well as Cartesian grid formats combined with boundary conditions. ICEM CFD also offers tools for post-processing and mesh optimization.
MeshSim	MeshSim is a software for fully automatic mesh generation direct from CAD models. MeshSim is available to software developers under an OEM arrangement so that you can incorporate advanced, automatic mesh generation within your CAD or CAE application. MeshSim BL is an add on module to MeshSim to allow the automatic creation of highly anisotropic volume elements adjacent to a surface.
Salome	The Salome platform provides, based on a software architecture using reusable components, is a generic platform for Pre and Post Processing, available as free software for numerical simulation. It supports interoperability between CAD modeling and computation software, makes easier the integration of new components for numerical computation. Salome functionality allows to; define geometrical models, import and export them using the IGES and STEP formats, define meshing of these geometrical items, import and export them, handle physical properties and quantities attached to geometrical items, import and export them in a reusable format, perform computations using a solver, read input data, configure the solver, write a result field, visualize result fields in 3D, 2D and export images of their visualization in an appropriate format, manage study schemes: definition, save/restore, manage computation schemes: definition, execution.
TGrid	TGrid performs advanced hybrid volume mesh generation using tetrahedra, pyramids, and prisms (wedges or hexahedra) and 2-D meshing with triangles and quadrilaterals. TGrid's robust, automated algorithms save preprocessing time and generate high-quality meshes for CFD analysis in FLUENT. Surface and volume meshes may be imported from GAMBIT, ANSYS, Catia, I-DEAS, NASTRAN, PATRAN, Pro/ENGINEER, Hypermesh, and more.
TrueGrid	TrueGrid is a general purpose mesh generation program with sophisticated relaxation and parameterization capabilities. It has been optimized to produce high quality, structured, multi-block hexahedral meshes or grids and serves as a preprocessor to over 30 of today's most popular analysis codes.
TurboMesh	TurboMesh is a powerful, easy to use, cost-effective FE mesh generator that runs on all Silicon Graphics workstations.
VGrid	VGrid is a computer program for the generation of three-dimensional unstructured (triangular surface and tetrahedral volume) grids in geometrically complex domains. Along with a graphical user interface utility GridTool and a grid post-processing program PostGrid, the Vgrid system provides a reliable tool for the fast and convenient generation of unstructured grids around complex configurations.
