you can find polynomial equations that is valid for steel.(its thermal expansion coefficient is high, its physical properties change with temperature )

as for water, pressure_inlet is tha you have defined as boundary condition ?

compare results with something that attained by experimental or etc.

Is problem that materials is set by setting pricewiselinear? and not polynomial?
I have velocity inlet, because velocity changes in time, but pressure stays the same.

but pressure stays the same.[/QUOTE]

the reason why I wrote as pressure inlet was you , because you wrote it and defined its 24.5MPa. I am trying to solve your problem.

I just think that the problem is relevant to precision. That's why it is better to write ''polynomial or polynomial piecewise equation in FLUENT.

Moreover, if your geometry has different cross sections, pressure always changes , I could not know what it is your geometry visually.

that's pretty good!, it must be something else the reason for mass imbalance.
