|type=[[ERROR]]
|message_desc=There has been an error when initialising the graphics card for a TUFLOW GPU simulation. This can occur for a number of reasons including:<br>
* Insufficient GPU memory (<tt>GPU ERROR: Required memory exceeds available GPU memory</tt>)
* Cannot find any CUDA enabled devices (<tt>GPU ERROR: nDevices requested less than 1</tt> or <tt>GPU ERROR: Non-cudaSuccess code returned</tt>)
* Compute capability is lower than required (<tt>GPU ERROR: Double precision requires compute capability of 1.3 or higher</tt> or <tt>GPU ERROR: Compute capability of 1.2 or higher is required.</tt>)
* Specified device ID does not exist (<tt>GPU ERROR: Cannot select device <requested device id>, must be in range 0 to <number of CUDA GPU Devices></tt>)
* A CUDA error occurred (<tt>GPU ERROR: Non-CUDASuccess Code returned)</tt>)
|suggestions=The console window above the ERROR 2440 message should give more information on the reason the error is occurring. For example in the image below insufficient RAM is available.<br>
If a CUDA compatible device is present in the
* The monitor is plugged into the GPU, if this is plugged into the motherboard (onboard graphics), the GPU device may be disabled.
* You have the latest nVidia drivers installed.
* PhysX is disabled or set to CPU.
* If you are using remote desktop software, this can cause issues with graphics devices - try running from the computer directly, not via a remote desktop.
