Changes

From version 2.8 to 2.9

• GiD_fWriteCoordinates*Block() Added coordinates block function to write array of coordinates with a single call.
• GiD_fWriteElements*Block() Added elements block function to write array of element's connectivities with a single call.
• GiD_fWriteResultBlock() Added result block function to write array of result values with a single call.
• GiD_PostGetVersion() added to return library version, and if hdf5 is enabled, hdf5 library version too.
• GiD_PostIsThreadSafe( format) : function which returns if format is thread-safe, i.e. several files with this format can be opened and written at the same time. For instance, some HDF5 compilations are not thread-safe, and can not be used to write several hdf5 files at the same time from the same program.
• gidpost-swig/ : to use gidpost library as python module.
• several corrected bugs in library.
• updated some C and Fortran examples to use the new GiD_fWrite*Block functions.
• updated examples/CmakeLists.txt to include and build more examples.
• updated documentation.

From version 2.7 to 2.8

• CMake updated and corrected to compile fortran90 example.
• Added functions to allow the user to add mesh and result properties / attributes:

   User defined properties defined inside Mesh or Result blocks

     HDF5: stored as properties/attributes (Name, value) of the current Mesh/N or Result/N folder

     ASCII / raw binary: stored as comments

       # Name: value

     Define the macro COMPASSIS_USER_ATTRIBUTES_FORMAT

     to have it like compassis wants:

       # ResultUserDefined \"%s\" \"%s\"      or

       # ResultUserDefined \"%s\" %s

  int GiD_WriteMeshUserAttribute(GP_CONST char * Name,GP_CONST char * Value);

  int GiD_fWriteMeshUserAttribute( GiD_FILE fd, GP_CONST char *Name, GP_CONST char *Value );

  int GiD_WriteResultUserAttribute( GP_CONST char *Name, GP_CONST char *Value );

  int GiD_fWriteResultUserAttribute( GiD_FILE fd, GP_CONST char *Name, GP_CONST char *Value );

From version 2.6 to 2.7

• Added support for MeshGroups ( BeginMeshGroup(), End..., BeginOnMeshGroup(), End...) in HDF5 as used in GiD, useful for dynamic meshes, refinement, multi-stage simulation, etc.
• All non implemented functions for HDF5 now return -1, i.e. all GiD_fXXX() functions.

From version 2.5 to 2.6

• Added support for ComplexMatrix Result types.
• More exhaustive example and some corrections.

From version 2.4 to 2.5

• Default format to print real numbers changed from "%g" to "%.9g" increasing the amount of significant digits to be printed in ASCII.
• New function GiD_PostSetFormatReal to allow change the default format of real numbers.

From version 2.3 to 2.4

• Allow write OnNurbsSurface results for iso-geometrical analysis

From version 2.1 to 2.3

• Allow use HD5 from FORTRAN interface
• Fixed bug with mesh group

From version 2.0 to 2.1

• Allow write complex scalar and complex vector results
• Write units of mesh or results
• Enhanced FORTRAN 77 and 90 interface to be more compatible.

From version 1.7.2 to 2.0

• New set of functions "GiD_fxxx" that allow specify the file to write, in case of have multiple files of mesh or results.
• Library rewritten in C avoiding C++ to be more compatible linking with other languages.
• Optional define of HDF5 to enable write postprocess files using the HDF5 library

• source/gidpost.cpp:

• GiD_OpenPostMeshFile should not write a header. Thanks to Janosch Stascheit <janosch.stascheit@rub.de>
• invalid access in GiD_BeginMeshGroup: should ensure that a valid mesh file object is available so etMeshFile() should be called
  before writing. Thanks to Janosch Stascheit<janosch.stascheit@rub.de> for providing the fix.
  2008/01/18

• source/gidpost.cpp: GiD_BeginOnMeshGroup should be "OnGroup\"%s\"" instead of "Group \"%s\"". Thanks to Janosch Stascheit
