What's new from version 10.1.6d to 10.1.8d
Preprocessing:

• VA + VBO: now circles and spheres are drawn
• Fixed bug when ForcedPoints were used in surfaces, using triangle quadratic mesh.
• Sphere generator preferences: circumvented the problem that caused rball preferences not to be saved.
• Fixed bug in boundary layer mesher. Sometimes not all the layers were generated.

Customization:

• GiD_MeshPost tcl function to create postprocess meshes enhanced
• GiD_Result, new 'gauss_point' sub command to manage gauss point definitions and 'result_ranges_table' to manage 'result ranges tables'.
• GiD_Graph tcl function to handle postprocess graphs.
• drawopengl: new suboption -getstring vendor|renderer|version|extensions
• GiD_Geometry list surface unrendered, to know the surfaces with problems to create its render mesh.

General:

• Now the splash window shows the packages being loaded at start time. Can be switched off in ConfigureProgram.tcl

Postprocessing:

• Import plug-in: added support for complex scalar and complex vector results, now they can be imported too.
• Graphs: corrected some bugs related to undefined results and importing graphs with no titles.
• Spheres: support for VA and VBO for faster drawing of nice spheres.
• Display vectors: corrected bug which caused gid to crash after this sequence: open multiple files + c.fill of resA + animate + displayVectors of resB + (zoom in) + animate AND c.fill was done using textures AND display of monochrome vectors.
• Standard (internal) gauss points (GP_TRIANGLE_1, GP_QUADRILATERAL_4, ...) should not be explicitly defined to be used.
• Delaunay: elements bigger than 10 times ( default) the mean size of elements are culled. Check Utilities --> Variables --> PostDelaunauCullBigElements to modify it.
• Macros: Added macro to create a result with the minimum, maximum or average value of a scalar for all steps.
• Create Results: added some single operator functions ( sqrt, log10, db10, db20, abs, exp, inverse (1/)) to Window-->Create Result...
• Graphs: new Tcl command GiD_Graph
• ** GiD_Graph show --> shows the graphs
• ** GiD_Graph hide --> hides the graphs
• ** GiD_Graph list --> list the existant graphs
• ** GiD_Graph clear --> deletes all graphs
• ** GiD_Graph get <graph_name> --> gets the graph data of "graph_name", the same as the create data.
• ** GiD_Graph delete <graph_name> --> deletes the graph "graph_name" causing an error if does not exists
• ** GiD_Graph create <graph_name> <label_x> <label_y> <list_x_values> <list_y_values> <unit_x> <unit_y> --> creates the graph "graph_name" with the provided information, causing an error if the graph already exists.
• Graphs: added discrete Fourier Transform of a Graphs. Uses the y values as real part and 0 as the imaginary part for the fft transformation. The graph created will use an index for the x axis and the real, imaginary or module of the dft result as the y axis. Check Options->Graphs>dFT->real , imaginary or module
• Graphs: added discrete Fourier Transform of a Graphs. Uses the x values as real part, and the y values as imaginary part for the fft transformation. The graph created will use an index for the x axis and the real, imaginary or module of the dft result as the y axis. Also the graph created can have as x axis the real part and as y axis the imaginary part of the dft result. Check Options->Graphs>dFT complex->real , imaginary, module or complex
• Read of postprocess files with GiD postprocess HDF5 format written by the GiDPost library, and postprocess files with Amelet HDF5 format.
• Create Results: added option for operators +, , * and / which now accepts a scalar or vector ( both can be complex) as second operand check the window: Window->Create Result...
• Create Results: added operators sqrt, log10, db10, db20, abs, exp, inverse (1/) which operates on one result. Only operators +, -, ** or */ accept scalars,vectors or results as second operand. SqrtAbs, Abs, Log10Abs, Exp, 1/ requires a result as second operator.

• New Create Graphs window: to create graphs from another ones, with following operators: +, -, *, /, sqrt, log10, db10, db20, abs, exp, inverse (1/), derivate, integral and fit. 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)
  • sale y values according to the number of items
  • get half the values, dft seems to be symmetric

• Graphs: corrected bug when doing line graphs on volumes
• Animation + several results: corrected bug when doing animation of several results combination iso-surface + contour fill
• Result state: corrected bug which caused the results menu not to be displayed when an incorrect step was present in the result state file (.vv)
• Integration graph: added tangential and un projected vector integration for lines and 2d
• Graphs: now, if the Amelet plugin is present, they can be exported to the Amelet HDF5 format
• Post preferences: circumvented the problem that overwrites the user preferences with original ones.
• Graphs: corrected bug in Options --> Graph --> Invert Graphs .
• Label results: now labels of vectors, tensors and local axes displays a letter with the component's name.
• Extract boundaries: corrected bug when creating boundaries from a quadratic element mesh
• VA + VBO: now quadratic elements are drawn as several triangles / quadrilaterals, instead of drawing them as linear elements if Utilities --> Preferences --> Graphical --> DrawQuadraticElements is set to "As lines".
