Time dependant cavitation pressure expression error

CFD-fellow · May 13, 2014, 11:38

Hi
when i write an expression and choose it for cavitation pressure the following error appears:

Parameter 'Saturation Pressure' in object '/FLOW:Flow Analysis 1/DOMAIN:stationary/FLUID PAIR:vapor | water/MASS TRANSFER/CAVITATION MODEL' has been assigned an expression that references the following unavailable variables: t
It seems that in cavitation pressure the variable t can not be distinguished, but why?
Whats the problem?

t is time. You cannot define saturation pressure as a function of time.
