Fluid Density

Unit: [M/L³]

Auxiliary Data parameter Fluid Density carries the current fluid density for each node of the model. It is available for density-dependent models only (Density Ratio or Expansion Coefficient not equal to 0, or nonlinear density-dependency on temperature is turned on the Transport Settings page of the Problem Settings dialog).

ρ₀ located on the Transport Settings page of the Problem Settings dialog is used as the basis to calculate the nodal density values.
