hello everyone: i use the cavitation model (fluent 6.1.2).i have some questions. 1:in fluent tut-files 17 (fluent6.1) they set the vaporization pressure 3540Pa,the operating pressure 0pa, but in tut-13(fluent 5) they set the vaporization pressure 80000pa ,the operating pressure 101325pa, in tut-16(fluent nov7, 2001) the set vaporization pressure 101175pa,operating pressure 101325pa. why they set the different vaporization pressure? 2: vaporization pressure is the function T, if in the case, T=300k the vaporization pressure should be const, 2365.5pa,(operating pressure 101325pa),why they set different? 3: please tell me how to set the vaporization pressure?

thanks!
