Dear All,
I created the model, but my display screen does not show the model. What causes this? Please help solve it.
Thanks
What do you mean by “created the model”?
I already have the model I need to simulate, but why can’t the display screen on the right show my model, grid, etc?
Is the VTK module loaded? Are there any messages at startup regarding VTK or OpenGL?
Please send a bug report - go to main menu, click Submit bug report and attach the zip file here.
Thanks.

This is a VTK/OpenGL problem, how do I solve it? Can I fix the OpenGL problem if I install a lower version of Mfix?
Here is the error code：

“GLSL 1.50 is not supported” means that your graphics card is too old. There may be some workarounds for this. Are you running remotely, or in a virtual machine?
Try searching this forum for “GLSL” and you may find some helpful suggestions.
