Units in acusolve

Hi experts,

 

I just wanted to confirm if I set the sketching unit in MMKS, does it have any impact on things like flow velocity? I mean if I change the unit to MMKS, then does that mean that the flow velocity is in mm/s? Or, it only affects the sketching (in mm) not the flow velocity(in m)?

Thanks.

    These dimensions concern only the Sketching part of HyperMesh CFD interface. They have nothing to do with solver setup. 

    AcuSolve setup in HMCFD still expects unit to be SI/MKS (Meter, kg, seconds, Kelvin, rad/s). 

    (AcuSolve in the strictest sense is unitless, just that material defaults in HMCFD are MKS, thereby other input also has to be MKS).
