[求助] CFX自定义材料！

CFX中自定义材料，density 随pressure变化，dynamic viscosity, thermal conductivity随temperature变化
我用插值函数定义了，在CFX-PRE里没有出现erro，并且在expression里plot出来的图和evaluate出来的值都是正确的。
但是到solver里一开始就会出现错误，问题好像还是出在我的属性定义里
我把problem贴一下，恳请高手指点！！！
The CFX expression language was evaluating: Density
The problem was:
Value below interpolation range
FURTHER INFORMATION
The problem was encountered in executing the expression for: padensity
The complete expression is:
Function 1(pabs)
The error occurs on sub-expression:
ction 1(pa
BACKGROUND INFORMATION
The error was detected at one location. The same problem may be present at other locations - that has not been investigated.
The following values are for the first location which has the problem
