Question

All,
I am using FunctionValuePostprocessor in Postprocessors to printout the values of a file read by PiecewiseMultilinear in Functions but it is seemingly not working (I got just zeros).
Please help. S.Thomas

Did you check the execute_on parameter? Is it being executed often enough?

[styyokuda]

Thank you, GiudGiud!
I set as
execute_on = 'initial timestep_end'

[styyokuda]

The file read by PiecewiseMultilinear in Functions has a form of
AXIS Y
xxx xxx xxx .... xxx
AXIS T
yyy yyy yyy ... yyy
DATA
zzz zzz zzz ... zzz
.
.
zzz zzz zzz ... zzz

So, we may have to sum the values in DATA for AXIS Y at each time step?
FunctionElementIntegral may help?

the FunctionValuePP is only computing one value of the function, at the origin (x=0, y=0, z=0) by default
if you want an integral then I agree FunctionElementIntegral does it
