What’s GiD

GiD is a universal, adaptive and user-friendly pre and postprocessor for numerical simulations in science and engineering. It has been designed to cover all the common needs in the numerical simulations field from pre to post-processing: geometrical modeling, effective definition of analysis data, meshing, data transfer to analysis software, as well as the visualization of numerical results.
GiD: from pre to postprocessing

GiD: a universal, adaptive and user-friendly pre and postprocessor

  • Universal: GiD is ideal for generating all the information required for the analysis of any problem in science and engineering using numerical methods: structured, unstructured or particle based meshes, boundary and loading conditions, material types, visualization of numerical results, etc.
  • Adaptive: GiD is extremely easy to adapt to any numerical simulation code. In fact, GiD can be defined by the user to read and write data in an unlimited number of formats. GiD’s input and output formats can be customised and made compatible with an existing in-house software. The different menus can be tailored to the specific needs and desires of the user.
  • User-friendly: the development of GiD has been focused on the needs of the user and on the simplicity, speed, effectiveness and accuracy the user demands at input data preparation and results visualization levels.

Applications fields

Typical problems that can be successfully tackled with GiD include most situations in solid and structural mechanics, fluid dynamics, electromagnetics, heat transfer, geomechanics, industrial forming processes, etc. using finite element, finite volume, boundary element, finite difference, meshless or particle based numerical procedures.

Why GiD

GiD reduces time and costs associated with numerical analysis through high performance data input and post-processing in the simplest computer environment.
High speed, high quality meshing and data input definition reduces the analysis time for complex geometries and large models.
Direct use of CAD data combined with GiD geometric modelling facilities reduces redundancy and costs associated with model development.
Easy interface with in-house software codes and CAD systems.
Reduced learning time and improves efficiency with an intuitive graphical interface.

User Interface

GiD is an effective and easy-to-use geometric user interface.
Completely menu-driven.
Versatile visualisation tools including rendering, pan, zoom, rotations, etc.
Multiple windows allowed.
Associative data structures so that the complete geometry database is updated whenever something is altered.
All analysis data can be defined on geometrical entities before the mesh is actually created.
User-defined and customable menus and interfaces for users own simulation software.
Complete set of tools for quick geometry definition.
Quick and easy definition of geometry with easy-to-use verification/visualization tools.

Who needs GiD

GiD is ideal to be used in a multi-user environment in universities, research centers and enterprises for development and applications of different numerical simulation programs.
Engineering companies wanting to unify their input data and results visualisation environment for a variety of numerical simulation codes.
Universities and R+D centers wishing to provide a multi-user environment for pre-postprocessing allowing the development and applications of a diversity of software in computational science and engineering.
Engineers and scientists wanting to have individual access to a powerful pre and postprocessing system for research and applications of numerical simulation codes either in UNIX workstations or in the simplest PC computer environment.

GiD general features

Multilingual: GiD environment is fully translated into English, Spanish, Japanese and Russian. Manuals are available into English and Russian.
Multiplatfom: GiD has been developed using C++, tcl/tk and OpenGL tools in order to give the best performance and portability on UNIX workstations and PC under Windows or Linux (on 32 and 64 bits), and on MAC OS X 32 bits.
Multiple license support: Three types of licenses are managed: attached to a computer, attached to a USB memory stick, or served from a remote computer (floating license).
Multiple calcuation options: calculation can be done locally or remotely: an application is provided to allow the running of the calculation remotely from GiD, and after the simulation get back the results to be visualised.


GiD has been developed by the International Center for Numerical Methods in Engineering (CIMNE), a research and development organization based in Barcelona (Spain). CIMNE was created in 1987, linked to the prestigious Universitat Politècnica de Catalunya. CIMNE specialices in the development and applications of numerical methods and software for the solution of a variety of problems in science and engineering. For details visit: www.cimne.com.
