• Page Setup window with information about the dimension of the image to be generated (in mm/inches and pixels).
• OffScreen: added ofscreen support for MS Windows and Linux, so that GiD can work in background (or batch queue), for instance to create long animations or a series of snapshots.
• OffScreen: added button in the Animation Window to create a batch file to be used with GiD in background or batch mode.
• Linux + ATI drivers: workaround to the problem which caused GiD to lock just after saving project or image with 'selection lines by software (emulation front buffer)' on.

Preprocessing

• Join surfaces: transfer conditions to the joined entities
• Cartesian mesh with non-uniform grid spacing and settings in preferences window
• Improvements in advancing front volume mesher (tetrahedra).
• In 3D boundary layer mesh generation, improved the way of deciding when to stop shifting a node, depending on the proximity of the close nodes in the isotropic mesh.

• Quadratic type of the model (variable IsQuadratic) loaded automatically when the model is loaded.
• Support for Vertex Arrays and Vertex Buffer Objects so that the drawing of lots of surfaces (in flat or smooth render mode) and meshes (in any render mode) is faster.

Postprocessing

• Preferences: new panel for Postprocess options:
  • Draw method: immediate mode, display lists, vertex arrays or vertex buffer objects
  • Enable or disable use of textures to draw Contour Fills
  • Enable or disable 'Results cache': ( Linux, Mac OS X) uses a portion of the main memory as 'cache' of results so that not all the results are loaded into GiD. The amount of main memory to be used can also be specified.
• Graphs: Point evolution and integral graphs bugs corrected. Now works also for 1 Gauss Point per element.
• Graphs: Integral works also for 1 Gauss Point per element.
• Graphs: new option to show the values of a graph into a table window.
• New option: Options --> Geometry --> Extract boundaries from shown volume and surface meshes; for each mesh creates a set with its boundary elements. The original mesh is left untouched.
• New option: Options --> Geometry --> Separate connected components from shown volume and surface meshes; for each mesh detects groups of connected elements and stores them in separate sets. For instance a single volume mesh which corresponds to three unconnected spheres will be separated into three sets each one containing the volume elements of a single sphere. The original mesh is left untouched. By default a maximum of 50 connected groups will be separated into separated sets. This limit can be modified with the variable Utilities --> Variables --> PostMaxNumComponents on the main's window the right menu.
• Display Window can be integrated into GiD's main window
• PGF Fonts: now True Type fonts are also used in Mac OS X, thanks to free type library actualization

• Render: Added two new fixed lights ( switchable separately): one orange and another blue, accessible through the right mouse button menu.
• Health check: added option to filter outlier vertices, for instance, to filter out vertices with coordinates bigger than 1e+32.
• Mesh read: for line elements, accept 'line' keyword ad element type in the mesh description line, besides the old keyword 'linear'.
• Animation Window: rewind button puts slider at the user selected starting step, and not the first step of the analysis.
• • New results types:
    • ComplexScalar: results with two components: real and imaginary part --> a + b · i
      1. ComplexVector: vectors with six components: ( rX + iX, rY + iY, rZ + iZ). If not provided, GiD will calculate the modulus of the real part ( sqrt( rX^2 + rY^2 + rZ^2), of the imaginary part ( sqrt( iX^2 + iY^2 + iZ^2) and of the whole vector ( sqrt( rX^2 + rY^2 + rZ^2 + iX^2 + iY^2 + iZ^2)
         1. DisplayVectors visualization draws both parts ( real and imaginary) when the modulus of the whole vector is selected
            1. LineDiagram draws both parts ( real and imaginary) when the modulus of the whole vector is selected.
               1. Stream lines can be done on the real part ( field) of the complex vector or on the imaginary part ( field).
               2. Look at the customization and reference manuals to get more information on how to specify complex numbers for GiD.

The "g1 fit g2" operator fits the bounding box of the second graph g2 to the bounding box of the graph g1. Also interpolator has been added: CubicSpline and Catmull-Rom Spline. Graphs can also be scaled and translated in order to match another one. This is the new window, and below some interpolated graphs examples.

• • Create Graphs: added dFT options:
    • create graph( idx, dft.real) or dft( idx, dft.imaginary)

• Node traces: now traces of nodes can be drawn. For a single mesh for the whole analysis, the node will follow the path of the deformed mesh across all steps. When several meshes are used for several time steps, then the nodes can follow the track of the original mesh or from the deformed one.
