Hi All,
when i read in a mesh (in my case from gmsh) that is written in millimeters, do i have to scale it by factor 1/1000 in foam to get the right values for U? And how is the surface flow in ParaView written? m³/sec, liter/sec, liter/min or something like that?

I hope one can help me,

Daniel

Everything inside OpenFOAM is treated in meters, kg, seconds, etc...
So, yes, you have to scale the mesh, if it has been generated in millimiters.
The surface flow in ParaView should match the units used inside OF, so I guess it is m³/sec

Thanks Francesco,
that's exactly what i needed to know. Can someone confirm that ParaView is also using the SI units?

ParaView is just a postprocessor, so it doesn't care about units.
This means it will preserve whatever values it receives.
