Buy SpreadDEM in the GiD shop

SpreadDEMNow you can purchase your SpreadDEM licences throught the GiD shop.

SpreadDEM is developed for MS Windows and can be purchased as a local or USB licence. The local version is a licence for a single PC/Laptop while the USB is a portable licence associated to a specific memory stick.

SpreadDEM is the first industrial numerical tool to perform virtual experiments of centrifugal fertilizer spreaders oriented to designers and producers of agricultural machinery.

Uses GiD as pre and post processor and takes advantage of the GiD customization tools to adapt the GUI appearance to SpreadDEM needs.

Based on DEMPack technology, a Discrete Element Method (DEM) software for bulk material simulation, the trajectory of every single fertilizer particle is evaluated from the hopper to their contact with the ground.

Perform virtual experiments of centrifugal spreaders with SpreadDEM

LogoNew

SpreadDEM is the first industrial numerical tool to perform virtual experiments of centrifugal fertilizer spreaders oriented to designers and producers of agricultural machinery. Is based on GiD and DEMPack.

Obtain spread patterns, transversal distributions of fertiliser and the coefficient of variation easily by importing your spreader geometry.

Improve your design by analysing the detailed flow of particles from the hopper onto the disc and from there to the ground, tracking individual trajectories, velocities and impact points.

SpreadDEM has been developed in CIMNE by the DEMPack team.

Easy to use

SpreadDEM provides a complete and practical solution to optimize the design of the spreading machinery becoming an alternative to trial-and-error experimental testing. Thanks to its easy-to-use interface, users are able to simulate in a few intuitive steps and with minimal training the most significant results for the fertilizer spreading.

Events

Past November, SpreadDEM team attended the¬†Agritechnica 2017, the world’s No. 1 trade fair for agricultural machinery, presenting¬†SpreadDEM to the leading manufacturers of agricultural machinery.

In February 2018 SpreadDEM team will attend FIMA2018, the 40 International Fair of Agricultural Machinery, that will take place on 20-24 February in Zaragoza, Spain.

9th GiD convention

gidconvention2018

The 9th GiD convention on Advances and Applications of GiD will be held from 6th to 8th June 2018 in Barcelona.

The objective of this event is to bring together users and developers of GiD pre/post processing system in order to exchange ideas and experiences on the generation of data for computer simulation and the graphic visualization of numerical results.

Furthermore, the 14th version of GiD will be released in the frame of the GiD Convention, and its new features will be presented.

One day will be devoted to workshop where advanced topics related with pre, post processing and customization will be discussed and, in the following two days, courses on GiD and calculation modules connected to it will take place.

The courses attendees will receive an exclusive 1 year GiD v14 professional licence for free.

New GiD developer version 13.1.9d

A new developer version have been released. GiD13.1.9d is ready to download from our webpage.

Check¬†what’s new in this version:

Preprocess:

  • Fixed bug in unstructured quadrilateral mesher that made GiD crashes in some cases where the surface to mesh had holes.
  • Added some check in octree volume mesher when there are forced points inside volumes, to avoid pathological situations that may lead the program to crash. These pathological situations happens when a forced point suposed to be inside a volume is actually onto some of its contour surfaces.

Customization:

  • New plugin ‘gid_slippy’ and gid_map package to import topography from tile map servers
  • New tcl GiD_Project subcommand¬†GiD_Project view ?clip_planes_x |clip_planes_y| clip_planes_z| clip_planes_margin| rotation_vector| rotation_factor |rotation_matriz| rotation_center| perspective_distance| perspective_ortho_near| perspective_ortho_far| perspective_factor| perspective_view| view_mode| render_mode| ligth_vector?
  • New tcl GiD_OpenGL draw subcommands to allow handle textures: -gentextures -deletetextures -bindtexture
  • togl widget renamed to gid_togl (to avoid name conflict with tcl3d package) and added drawing callbacks to be defined in Tcl instead of C (-createcommand, -displaycommand, -reshapecommand, -destroycommand, -overlaydisplaycommand, -timercommand)

New tool for automatic modeling of arch dams

Researchers from CIMNE, including Javier San Mauro and Fernando Salazar, have developed an interactive tool for automatic predimensioning and numerical modeling of arch dams. The aim of this tool is to perform in an automatic way the generation of the geometry, the mesh, and the assignment of the boundary conditions.

This tool represents an innovation to design FEM models of double-curvature arch dams in front other solutions based on recommendations of traditional technical documents without taking into account the possibilities of computer-aided design.

Another characteristic is the tool is integrated with the pre and post process software GiD, which allows taking advantage of its functionalities, such as mesh generation and results analysis. It is also coupled with a specific application for thermo-mechanical analysis of dams, developed in Kratos Multiphysics. The whole design process can be followed in a unique environment, because the structural response of preliminary designs can be computed and the results considered to refine the dam geometry.

The work will be presented during the 14th ICOLD International Benchmark Workshop on Numerical Analysis of Dams. The Workshop is been helding from the 6th to the 8th September 2017 in Stockholm, Sweden.

A preliminar version of this work was presented in the past GiD convention.

New GiD Mesh Library

logo-gid-ml

GiD team is proud to anounce the release of the GiD Mesh Library (GiDML).

The GiDML is a collection of libraries (modules) that offers a wide range of meshing functionalities.  It contains three main families of modules: mesh generation, mesh edition and mesh analysis.

Modules

GiDML is structured in different modules, each one of them focused on specific meshing features. Each software should choose the module it wants to be connected to, depending on its needs. The library is permanently in evolution, including new modules in the future, to cover a wide range of meshing needs.

Why use GiDML?

GiDML is a solution for software developers who needs to integrate meshing features in their code.  GiDML includes most of the meshing featu­res of GiD pre and postprocessing system, as well as and some new ones. So the developers will take advantage fo theses capabilities.

It is mainly developed by the GiD team, but is opened to other developers to integrate their own module. The developers will benefit with several advantages such as the access to our dissemination channels.

GiDML is a library without graphical user interface. Developers can access for free and without limitation to an input/output module, which provides the API functions to get and set the data from and to the corresponding GiDML modules.
