CFD/0/p

Hi !

I have such a stupid question I wonder if this is the right place to ask !
The pressure directory CFD/0/p contains pressure setting.
Since I see 1.e05 in both Hopper and Ergun testcases, I assume it uses Pascal Unit (as 1 atm = 10^5 Pa).

Since [Pa]=[kg/(m*s^2)], bracket unit should be [1 -1 -2 0 0 0 0] and NOT [0 2 -2 0 0 0 0], isnt it???

Hello,
In OpenFOAM, usually P denotes kinematic pressure or P/rho with dimension of m2/s2.
