Display grafic problem - Model turns after some seconds to black

[LostNameQuestion]

Hallo community

I have got Autodesk Simulation Mechanical 2015. It is running on a DELL Latitude E6540. The graphics card is an AMD Radeon HD 8790M and Intel HD Graphics 4600. Processor is Intel i7 4800MQ 2.70GHz. Running on Win7 Ultimate.

When I load a model, it opens without any problem. After some seconds the model itself turns to black. If you pan and rotate the model you can see the different parts of the model with its different colours and the mesh. But after some seconds the model turns to black again.

I had a similar problem with the background colour which changed from light grey to dark grey after some seconds. I fixed this problem by changing the background colour in the opions of "Autodesk Simulation Mechanical 2015".

Changing the shadows and lighting options didn't solve the problem.

I also tried to switch off the hardware acceleration option of the graphics card in the Windows 7 settings. Unfortunately this setting is not available.

Does anybody know how to solve the issue of the black model?

Thanks in advance

Hi Jochen,

There has been some discussion in the past on this topic. If you search "rotate black" or "black screen" you'll see some of those discussions.

I have had the same problem in the past. My issue was that Simulation was not using the high-performance graphics card, rather the on-board Intel graphics, which seems to have some compatibility issues. In Simulation, go to Tools/Application Options/Graphics/Hardware and click information. It should show that you are using the AMD graphics card. Enable OpenGL acceleration should also be selected. If it shows that you are using another graphics card (e.g. Intel), then you should go to your AMD graphics card control panel and force the Autodesk Simulation app to use AMD graphics card (I set all my apps to use it - why not?), then restart Simulation. You may need administrative priveleges on your computer in order for Simulation to accept this change.

Hallo Stefan Thanks for your replay. Your tip solved the problem. I just selected to proper grafic card as "high performance and always ON". Thanks
