When installing the Fluent software first,I can use it ,but the next day I found when I wanna to display the contour graphic ,grid ,vector ,there show the something like these following: --------------------------------------------------- Error message from graphics function Update_Display: Unable to Set OpenGL Rendering Context

Error: FLUENT received a fatal signal (SEGMENTATION VIOLATION). Error Object: () ---------------------------------------------------- I want sb. help me out.Otherwise the Windows 2000 system must be reinstalled.

i had some problems with a graphic card before (couldnt see any figures and grids) and i could fix it by starting Fluent with the command: /pathtoyourfluent.exe/fluent.exe -driver msw

(which sets the graphics driver to the microsoft driver as far as i know) maybe this helps... Stefan
