Purpose

Set reference pressure and, for thermal cases, the buoyancy reference temperature and gravity vector.

Steps

  1. Open Settings → Operating Conditions.

    Operating conditions controls

  2. Enter the reference pressure. With heat transfer enabled, select Buoyancy if required.
  3. For buoyancy, enter the reference temperature and gravity components, then click Apply.

Inputs and units

Input or valueMeaningUnits
Reference pressureAbsolute reference pressure.Pa
Reference temperatureReference value for buoyancy.K
g(x), g(y), g(z)Signed gravity components along the global axes.m/s²

Limitations

  • This dialog currently uses the SI units shown above. Buoyancy controls are enabled only with heat transfer; temperature and gravity inputs are enabled when Buoyancy is selected.
