Issues of compile in /example/turbulece/channel3d running in GPU

[Yuji]

Dear Adrian,
I got some error in channel3D using nvcc, and fixed this error following this post(https://www.openlb.net/forum/topic/issues-with-time-averaged-velocity-field-in-turbulence-model-running-in-gpu/). Thank you.
However I got additional error that I cannot solve. How can I solve it?
error is below;

Thank you.

These overload conflicts when using nvcc are caused due to the using namespace olb::utils; at the top of the case (which should no actually be an issue in this context but is bad style anyway). For more details you can read this thread.

However this won’t get turbulence/channel3d running on GPUs as it is not included in the GPU-enabled examples for release 1.6 (you can compare the release notes for a full list). The reason for this is the usage of a old implementation of a wall function that was written way before the GPU port without a focus on performance. Better versions are being worked on internally but are not yet included in the release.
