Bouyancy Unit Error
 

Hello everyone, I am new for Ansys and trying to make an analysis of a rotating blade. After I set up Bouyant Option, the error appears that Invalid units ('dimensionless') set for parameter 'Gravity Y Component' in object '/FLOW:Flow Analysis 1/DOMAIN:Fluid/DOMAIN MODELS/BUOYANCY MODEL'. Expected units: 'm s^-2'. Here is the cll;

FLOW: Flow Analysis 1
DOMAIN: Domain 1
BOUNDARY: Openning
Boundary Type = OPENING
Location = Openning
BOUNDARY CONDITIONS:
FLOW DIRECTION:
Option = Normal to Boundary Condition
END
FLOW REGIME:
Option = Subsonic
END
MASS AND MOMENTUM:
Option = Static Pressure and Direction
Relative Pressure = 1 [atm]
END
MESH MOTION:
Option = Stationary
END
TURBULENCE:
Option = Medium Intensity and Eddy Viscosity Ratio
END
END
END
END
END
COMMAND FILE:
Version = 17.1
END

I don't know what i should do. Could you help me?

Bouyancy Unit Error
 

I have figured out the problem. I had changed the value of 9,81 to 9.81 of Gravity Y Drin. and the error have dissappeared, interesting.
