Menu: Files->Postprocess


This chapter describes some relevant aspects of the postprocessing step and the way to load results from a numerical analysis into GiD.

In GiD Postprocess you can study the results obtained from a solver program. GiD receives mesh and results information from the solver module, and if the solver module does not create any new mesh, the preprocess mesh is used.

The solver and GiD Postprocess communicate through the transfer of files.

The solver program has to write the results in a file that must have the extension .post.bin, .post.h5 or .post.res and its name must be the project name. If the solver writes a mesh, the file must have the extension .post.msh ( see POSTPROCESS DATA FILES from Customization Manual) or be writen inside the .post.bin or .post.h5 file. Older extensions like .flavia.bin .flavia.msh or .flavia.res are deprecated.

The extensions .bin, .h5, .msh and .res can be opened in post-process, but only files with the extensions .post.bin, .post.h5. .post.msh and .post.res will automatically be read by GiD when switching from pre- to post-process mode in GiD.

Please review the General Aspects --> Files Menu (Files Menu) section to learn how to open files in post-process mode and which are the supported import and export formats.

There are two ways to postprocess inside GiD:

  • Postprocess inside a GiD project: Start GiD and open the GiD project (ProjectName.gid) you want to postprocess, and then select the Postprocess option from the files menu or click on the pre/post toolbar button. This way the file, or the old ProjectName.flavia.res, will automatically be read by GiD, along with the file, or ProjectName.flavia.msh, if present.
  • Postprocess other files: Start GiD and select the Postprocess option directly from the files menu or click on the pre/post toolbar button. Now open the pair files OtherModel.msh and OtherModel.res.

A list of the supported elements and results can be found on Postprocess mesh format: from Customization Manual.

Once inside the postprocessing component of GiD, all the visualization features and management options of the preprocessing section are available: Zoom, Rotate (Rotate screen/object axes, Rotate trackball,etc.), Pan, Redraw, Render, Label, Clip Planes, Perspective, etc.

Refer to the POSTPROCESS DATA FILES section of the Customization Manual to learn about the supported formats and extensions.

Note: There is no need to load a project into GiD to use its postprocessing facility; you can open mesh and results information directly from GiD Postprocess (see Files Menu).
