  Hi,
  
  I am very new to Ansys Discovery Live, yesterday I installed the student version and wanted to start the samples, like the truck. In your tutorial videos the Solver starts from itself, but when I open the samples, nothing happen! Even if I click on the Start Solver Button no fluid simulation starts. Moreover if I change some the pressures or temperatures, errors come up but change the values anyway.
  
  Please help!
  
  Best regards Tim

  Hello tijowi Can you send a snapshot of what you are seeing after you click the sample truck example? I guess there could be issue with graphics card compatibility. Can you run this compatibility tool and check whether your machine's graphics card is compatible with Discovery Live?

  Hello, Firstly thanks for the quick answer, I installed the tool and I found out that my NVIDIA Quadro 4000 hasnt enough GPU Memory (I need 4GB but I just have 2GB) I think thats the reason why I could not the a fluid simulation. Eventhough I send you a screenshot right after I opened the truck example. Best regards

    tijowi So you need to upgrade the hardware for running Discovery Live.

  Its me again,
  
  I upgraded my GPU to a NVIDIA Tesla K40m but now I have a probelm with the CUDA Version. What have I to do now? Which GPUs can I use because this is my third GPU which I build in.
  
  Would GeForce GTX50-80 work with Discovery live?
  
  Best regards

    tijowi Please try upgrading the graphics drivers from NVIDIA Driver Downloads.
    
    You may also want to install the CUDA toolkit located here:
