Hi @ProjectPhysX ,@FluidX3D
,
I would like to calculate your CFD by only CPU.
Could you tell me how to do it?

Best,

Install the Intel OpenCL CPU runtime (Windows: win-oclcpuexp-2022.14.8.0.04_rel.zip, Linux: oclcpuexp-2022.14.8.0.04_rel.tar.gz & install guide). This works for both Intel and AMD CPUs. Once installed, your CPU will show up as an OpenCL device, and you can select it in the command line with either ./make.sh 1 or bin'/FluidX3D.exe 1, where the "1" is the device ID of the CPU (might be a different number for you).

Performance will be significantly slower, but the benefit is that you likely have more RAM, so you can do larger grid resolution.
