Hello
I’m considering to use OpenGeoSys in a bioremediation project. At the moment I’m testing its geometry generation capabilities. I understand that it uses Gmsh to generate meshes?
As a first step I’m using the example files in http://www.opengeosys.org/resources/examples , specifically the file GROUNDWATER_FLOW.tar.gz.
The version of gmsh i’m using: 2.9.3
The version of linux: Fedora 21 (4.0.4-202.fc21.x86_64 GNU/Linux)
I downloaded two versions of the ogs data explorer for linux from: https://www.opengeosys.org/ogs-5/ and http://docs.opengeosys.org/download#latest
The name of the first version is : ogs-6.0.0 Beta-Linux-2.6.32-431.el6.x86_64-x64
The name of the second version is: ogs-6.0.1-398-g4b6c26d-Linux-2.6.32-504.8.1.el6.x86_64-x64
with both versions I have tried to open the file “q_quad.gli” included in the example package mentioned previously and the results seems to be the same.
The output after reading the file is:
info: GeoLib::readGLIFile(): open stream from file /home/zerpiko/GROUNDWATER_FLOW/q_quad/q_quad.gli.
info: GeoLib::readGLIFile(): done.
info: GeoLib::readGLIFile(): read points from stream.
info: GeoLib::readGLIFile(): ok, 5 points read.
info: Geometry “q_quad.gli” built. 5 points added.
info: GeoLib::readGLIFile(): read polylines from stream.
info: GeoLib::readGLIFile(): ok, 2 polylines read.
info: GeoLib::readGLIFile(): tag #SURFACE not found.
info: 2 polylines added.
It seems that the file is read correctly, except for the line “info: GeoLib::readGLIFile(): tag #SURFACE not found.”. What is the reason for this?
Then after specifying the path to gmsh I go to Tools->Mesh Generation and in the new window I transfer the geometry file q_quad.gli from “Available information” to “Employed information”.
In the second tab “Advanced” I leave the default options (Adaptive meshing) and untick the “Delete GMSH geo-file after generating mesh” so that I can check this file by myself. After accepting these
options the terminal output is:
info: Start meshing …
info: GEOObjects::getStationVec() - No entry found with name “q_quad.gli”.

It seems like Data Explorer is not finding the correct file? And then, the generation of the .geo file is incorrect, in this case is empty, in others with different .gli files it has incomplete content.
Do you have any suggestions?
