Hi all,

I have a moving wall which should move according to Bernoulli's equation:
V=(Dynamic Pressure*2/density)^0.5.

I have a multiphase flow, the pressure to have in account is exerted near the wall ('plane-8' in my model) in phase-1.

I am writing this in the expression field as:

"(AreaAve(<DynamicPressure>,<'plane-8'>)*2/Density(phase='phase-1'))^0.5"

But I keep having a syntax error which I cannot identify:

"Cannot plot expression: File "<string>", line 1
(AreaAve(<DynamicPressure>,<'plane-8'>)*2/Density(phase='phase-1'))**0.5
^
SyntaxError: invalid syntax"


I am using Fluent 2023R2 (pictures attached).

Thank you so much.

M.
