Keywords in .tcfd file
In this section, keywords used in .tcfd file to setup cavitation modeling are described. See example of setting for water at atmospheric pressure and 20°C:
referencePressure 101325
referenceTemperature 293.15
referenceDensity 998
cavitationRisk yes
Values are expected to be in Pa, K and kg/m
, respectively. For turning on Multiphase cavitation, following keywords are necessary:
referencePressure 101325
