Hello,
I'm trying to obtain the temperature average on the first of 2 bodyes, reading manuals I tryed to do as follow
Solver 4
Exec Solver = String "after timestep"
Equation = String SaveScalars
Procedure = File "SaveData" "SaveScalars"
Filename = File "T.dat"
Variable 1 = Temperature
Operator 1 = String int mean
End
I put
Save Scalars = Logical True
under Body 1
I obtained results with no errors.
The problem is that if I remove "Save Scalars = Logical True" steatment, or I put it under Body 2, I heve EXACTLY the same results.
I read about a "volume" parameter to set, but I don't know where...
Thanks for evaluating my problem!

Re: int mean
Hi Roberto
The 'save scalars' flag applies only to bounaries and operations therein. Of course it could apply to bodies, but currently it doesn't.

Hi Peter,
thanks for reply!
So by the moment "int mean" works only on the whole geometry?
If it's so I can turn around the problem and calculate the heat flow entering the water each time step.
Anyway i'm deeply impressed by the power and versatility of this software!
Thanks again, Regards
Roberto

Re: int mean
Hi
You might use the operator "potential energy" which needs also a coefficient which refers to a name of a material parameter, say "Coefficient 1 = String MaterialActive". And the in the Material sections say "MaterialActive = Real 1.0" where you want to integrate and zero where not. Not pretty, but might do the trick.

Re: int mean
Hi Peter,
I'm almost there...
I did
Solver 3
Exec Solver = String "after timestep"
Equation = String SaveScalars
Procedure = File "SaveData" "SaveScalars"
Filename = File "T2.dat"
Variable 1 = Temperature
Coefficient 1 = String MaterialActive
Operator 1 = String potential energy
End
with the string
MaterialActive = Real 1.0
on materials, now I can control where to integrate.
At this point how can I get the average temperature?
Thanks again
Regards
Roberto

Re: int mean
Hi
Luckily the operator 'volume' eats the same coefficient so you can say
And the computation of the mean is then easily done manually.

Code: Select all
Variable 2 = Temperature
Coefficient 2 = String MaterialActive
Operator 2 = String volume
