Using MRT with GPU

[sfraniatte]

Hello,

I can’t get the MRT method to work with the Smagorinsky model on GPU (e.g., with the aorta3d example), but it runs fine on CPU in parallel mode with the latest version of OpenLB. Everything worked correctly with version 1.7. I’m using CUDA 12.9, and everything works properly with the BGK method.

Best regards,
Sylvain

I forgot to mention that it’s only the outlet pressure condition that doesn’t work (the flow remains zero) with the MRT method.
