Default Graphical Error (OpenGL)
Posts: n/a
I have a problem with the graphics in FLUENT. When I try to open a graphical window (i.e., contour plot, grid plot etc.) I get the following error message: "Error message from graphics function Update_Display: Unable to Set OpenGL Rendering Context"

I should mention that this problem started about the time I installed MATLAB on my computer. When I run MATLAB I get the following message: "Warning: Could not query OpenGL".

Anybody how knows the solution for this problem?

I think your video card/driver is not functioning in OpenGL mode if you are using Fluent.

If you are using Windows 2000/XP you can try this:

1. Open up Control Panel, System, Advanced, Environment Variables. 2. Under User Variables or System Variables, click the New Button. 3. In the Variable text box type: HOOPS_PICTURE 4. In the Value text box type: msw/win 5. Click OK.

Now Fluent should use software rendering instead of OpenGL.

Karl: Thank you for your response but it does not seem to work. I get the same error message as before.


P.s. I'm using Windows XP D.s.
