To install this VC++ CAD G-System on Windows, click this --- G-System Install 2010-09-24B

NOTE: This installs properly only for Windows Vista and Windows 7.  (Total size:  about 6MB)
           G.EXE will be created on your desktop (Start/All Programs/G-System/G.EXE).
           Also, if you had installed this before, you must uninstall before attempting a new install.
           (Note: Windows XP not supported.)

Finally succeeded in making this G-System CAD downloadable from this website - just click
G-System Install here.  As for Getting started, please look at Mouse Usage under User Guide on the left pane of Home page.


1. Bring up G.EXE. Click a command icon on the left with 4 small boxes (red,green,blue,yellow) - its tooltip says "CFD Ibitsu Test".
2. Click TAB-KEY once or twice or three times, then hit SPACE-BAR. (This gives you 3 different pre-defined scenarios)
3. Continue to hit SPACE-BAR many times. I am inserting a box in an existing domain and discretizing the domain accordingly - to maintain hex structure.
4. Eventually, the domain is gridded (meshed) and I show grids by moving IJK planes.
5. Click TAB-KEY to toggle IJK planes and continue to hit SPACE-BAR.
6. Prompt messages on the lower desktop may be of help.
7. You can now go to a separate GRID command (lower icon) and key in a number of grids per region (say 5 or 8l).

Technical Notes

I used Visual Studio 2008 Windows Installer (under Windows 7) to create this setup program for this CAD system.

When I installed this on my Windows XP desktop machine and ran it, I hit a snug -  a runtime error "Entry Point Not Found" << The procedure entry point _ftol2 could not be located in the dynamic link library msvcrt.dll. >>  This is due to incompatible dlls in XP. So this software has to be installed above Windows Vista level.
