[GiDlist] Post process tools

Good morning, GiD team

I need to do some operations in post process.
Durind the last GiD conference I was told they were available, but I don’t
know how to do them:

1.- Take parts of a postprocess mesh to work with it
separately. For example, if I make a cut over a mesh, and then I want to
analyze a part of it for calculating the integral of some of the results.
Is it possible to save a part of a mesh as an independent mesh, and then
open it with GiD and work with it? How?

2.- I know I can convert a
isosurface into a cut, and then into a mesh. Is it possible to use this
isosurface/cut/mesh to cut another (volume) mesh? How?

3.- How can I
import a preprocess mesh to the post process?

Thanks

Hello,

  1. There are several options to achieve this:

Top menu bar – Divide by selection : select the elements you want and create a new mesh with these elements

Top menu bar – Divide volume sets / surface sets : create a new mesh whose elements are on one side of a plane defined by the user

Top menu bar – Divide lines : create a new mesh with the edges of the surface elements which lie on one side of a plane defined by the user

To save the meshes: Top menu bar – File – Export – Post information – ASCII files / Binary ( whole model = mesh + results) / Binary (only results)

Top menu bar – File – Export – Post information – ASCII boundaries : writes a mesh file only with the boundaries of the meshes

( so for a tetrahedral mesh this option will write the triangles boundaries, for a triangle mesh it will write the lines of the boundaries)



2. To convert an isosurface to a cut-mesh: Top menu bar – Options – Iso surfaces – Convert to cuts

Top convert a cut to a surface mesh: Top menu bar – Do cuts – Convert cuts to surface sets

At the moment it is not possible to use one surface set or isosurface to cut another mesh.



3. to import the preprocess mesh into Post:

  1. you need to export the preprocess mesh into ascii file

  2. then in postprocess read, or merge, the mesh.

But when GiD switches from the preprocess parto to postprocess, the mesh in the preprocess part is also present in the postprocess part.

¿What exactly do you want to do?

Best reagrds,



Miguel Pasenau

Hello,

the link to the GiDpost-library

http://www.gidhome.com/downloads/Other_gid/Tools/gidpost1.70.zip

given on the download page is not working. Browsing the ftp-server, I found the library at

ftp://www.gidhome.com/pub/Old_gid/Tools/gidpost1.70.zip

Do you have any plans to release an updated version or to enhance the library in order to
read in GiD-files as well? This would be a very important feature for us!

Regards,
Andreas Hauck

Hello,

Thanks for the information, now the link of the web is fixed.

About your question, our develop GiDpost library now has a new option, it’s
possible to write GiD results using the HDF5 library.
Future GiDs will be able to read this GiD postprocess hdf5 files,
and also third part programs like yours could be able to read this kind of
files, from C/C++/FORTRAN using the HDF5 library, and from Tcl/Tk using the
hdf5 package wrapping this library that we included with GiD 10.

Note: the related ‘develop GiDpost library’ is not ready to download, the
version that you can download is the 1.70 that not include this hdf5 new
feature.

Regards

Enrique
