How can I monitor forces during my simulation using Newtons instead of dimensionless coefficients in FLUENT?
|
FLUENT always monitors forces using dimensionless coefficients. These are defined as
Coefficient = Force/(0.5ρV2A) (1) Where Force = Viscous + Pressure Force (on selected boundaries) ρ = Reference Density V = Reference Velocity A = Reference Area Hence, the user needs to make the denominator in (1) equal to unity to get FLUENT to report force in N. A simple way to do this is to place ρ= 2 kg/m3 V = 1 m/s A = 1 m2 In the Report -> Reference Values panel in FLUENT. The only reference value which requires changing from the default value is the Reference Density to 2 kg/m3. |
