Dear all:

I am using the following code in sample dict to obtain wall pressure at the left and rightwall of the tank as it is moving back and forth:

fields (alpha1

interpolationScheme cell;

type patch;
patches (leftWall);
interpolate true;
triangulate false;

type patch;
patches (rightWall);
interpolate true;
triangulate false;

One of the result I get is as follows:

# p POINT_DATA 544
# x y z p
-0.05 0.499219 -0.35 103304
-0.05 0.499219 -0.34 631 103304
0.05 0.499219 -0.34 631 103304
0.05 0.499219 -0.35 103304
-0.05 0.499219 -0.34 262 103267

My question is what is the unit of P? is it pascals or something else? I am using the metric system (kg, m, sec). I look forward to an answer. Thankyou.

I guess the unit is m^2/s^2. OpenFOAM uses pressure divided by rho as you can see in your pressure boundary conditions file.

Best regards,
