Hi,

I have a question regarding the units of pressure in a 2D simulation with a planar geometry. This would be a slice of a 3D geometry for which I know the inlet pressure (in psi or Pa). What should I apply for the 2D case? Should I apply the same pressure value or scale it up by multiplying it with the width dimension?

Thanks a lot.

the action of the [force]/[area] is provided in 2D by considering the area obtained by the 2D line x 1 unit in the third (normal to plane) direction.

Hi Filippo,

Thanks for the feedback. In that case, the original pressure value would be retained for the purpose of applying inlet boundary conditions.
