GiD+OpenSees Interface

openseesinterfaceThe GiD+OpenSees Interface introduces a long-awaited graphical interface for the popular open source finite element software OpenSees by seamlessly connecting its text-only solver to the user-friendly general graphical pre/post processor GiD. It is available as an add-on (problemtype) for GiD and delivered as open source, under the GNU General Public License.

The interface currently provides a comprehensive set of materials and 1D/2D/3D elements for linear and nonlinear static analysis and will be subsequently extended to time-history analysis as well.

iGP: PFLOTRAN interface

iGPiGP is the interface between GiD and PFLOTRAN and is developed by Amphos 21. GiD is a powerful universal, adaptive and user-friendly pre and postprocessor for numerical simulations in science and engineering and is developed by the International Center for Numerical Methods in Engineering (CIMNE), a research and development organization based in Barcelona (Spain). PFLOTRAN is an open source, state-of-the-art flow and reactive transport code.  iGP provides a powerful and  user-friendly pre and post-processing environment to PFLOTRAN. In iGP, the user can define different regions, set different materials, apply different boundary and initial conditions, mesh complex geometries (using structured, semi-structured or fully unstructured grids), run PFLOTRAN and post-process the results.

Current capabilities of iGP are:

  • Work with all the 3D element types available on GiD (e.g. tetrahedrons, triangular and rectangular prisms, etc.)
  • Fully compatible with structured, semi-structured and unstructured meshes.
  • Apply boundary conditions directly into the geometry.
  • Create and customize materials with different properties and apply them to geometrical entities.
  • Automatically generate PFLOTRAN input files and run them on the user’s machine.
  • Post-process the results with contour plots, scatter plots, animations, etc.

LS-DYNA Interface

GiD LS-DYNA Graphical Interface is an application acting as a bridge between the pre/post processing program GiD and the commercial nonlinear dynamic solver LS-DYNA.
LS-DYNA is a general purpose finite element code used to analyze the large deformation response of structures (including structures coupled to fluids). Specialized capabilities for airbags, sensors and seatbelts have tailored LS-DYNA for applications in the automotive industry.

GiD LS-DYNA Interface, which is compatible with GiD 9 and LS-DYNA v. 971, provides a completely graphical environment for several types of structural simulations. However, the product is focused on crash test problems and necessary tools for seatbelt and airbag definitions have been implemented.
GiD LS-DYNA Interface is powered by a new Toolkit for problem types creation (developed by Compass Ingeniería y Sistemas S.A.). Thanks to this new system, problem data is always displayed on the left of the screen during Pre and Post-Processing and the Interface is based on groups’ concept. A group is a list of geometrical or meshing entities that are referenced by one or several conditions, and the Toolkit provides the user all the tools to manage and edit them.
On one hand, Experienced users will find a revolutionary way to define structural problems with LS-DYNA, taking profit of GiD user-friendly behaviour. Problem edition will be easier than ever and all GiD Pre and Post-Processing tools are also available.
On the other hand, Beginners will find an application with a very intuitive way to completely analyse a structural problem.
INTERFACE CAPABILITIES:

  • Handles discrete, beam, shell, solid, seatbelt and airbag elements
  • Several material types vailable (elastic, rigid, isotropic, anisotropic, fabric, plastic, viscoelastic, springs, dampers, etc.)
  • Single and Master & Slave contacts definition
  • Dynamic loads and constraints
  • Several Joint types available (spherical, revolute, translational)
  • Fully GiD postprocessing functionality

Nastran Interface

NASTRAN Interface: Statics and dynamic interface for NASTRAN analysis program. Supports MSC/NASTRAN, NE/NASTRAN and MI/NASTRAN
The NASTRAN problem type is designed to be a bridge between NASTRAN codes and the GiD pre/postprocessor. NASTRAN Interface uses the power tools of GiD mesh and the easy way to assign conditions directly over geometry.

With these special capabilities, NASTRAN generates input files easy and fast. Working with beams is very intuitive and automatized, and the conditions can be applied directly to the line before meshing and creating linear elements. Shell and solid elements take advantage of the powerful GiD meshing features.
Supported NASTRAN elements:

  • Bar
  • Beam
  • Curved Beam
  • Tube
  • Viscous Damper
  • Spring
  • DOF Spring
  • Shear Panel
  • Membrane
  • Bending only
  • Plate
  • Plate strain
  • Tetrahedron
  • Hexahedron

For NASTRAN old users, this way of defining loads and constraints may be new, but these improvements will make the work much easier.
News: First version of the interface that can deal with statics and dynamics analysis with all the NASTRAN elements.

Abaqus Interface

GiD-Abaqus Interface allows the user to pre and postprocess Abaqus problems in a single and completely graphical environment, thanks to the powerful tools of GiD. Geometry can be directly created with the GiD CAD tools or imported and repaired thanks to a standard format (please refer to the GiD manual in order to get more information). Before or after meshing, the user can apply several conditions to the model:

  • Define sets of nodes
  • Define sets of elements
  • Define sets of surfaces (by nodes or face elements)
  • Specify the formulation of every element
  • Create and apply some elastic materials
  • Define local coordinate systems

After running the simulation, all the Abaqus results can be postprocessed in GiD by reading the resulting Abaqus Database (ODB)
