Geometry units/what is the real-life size of geometry
 

Hey guys,

I'm new to OpenFOAM and trying to understand its internal workings. My question is- how do I know how big my geometry is in openFOAM? Let's say I build a cube geometry using gmsh and import it into openFOAM. The point coordinates of the front face are A(0,0,0), B(2,0,0), C(2,2,0), D(0,2,0) and etc for other faces of the cube. I would like to know, what is the unit of that length 2...is it meters, millimeters, or is it not defined that way at all?

Any help would be greatly appreciated, thanks!

It'll be in meters by default.

Ok that makes sense- thank you!
