It looks like recent OF versions (v9/v10/dev) has excluded fiedMinMax from the functionObejcts?

Can anyone help how to use this in v9/v10/dev?

Thanks!

Hi E,
search for cellMin, cellMax in multiphaseEulerFoam/laminar/systemInjection.


These are for scalar variables; for vector variable you can use cellMinMag & cellMaxMag.


Strange part is that we dont get a printout in terminal using these. anyone has any idea?

I started playing around with OpenFOAM 9 today and I came up with the same question.

After a lot of searching, I found at OpenFOAM release notes (under Function Objects):

https://openfoam.org/release/9/

this commit link:

https://github.com/OpenFOAM/OpenFOAM...b34102fff0c63f

in which it is stated that fieldMinMax has been removed .
Instead, you can use volFieldValue and surfaceFieldValue.


As a consequence, the workaround I used was to employ two separate functions, one for min and one for max value, like:


min_U
{
type volFieldValue;
libs ("libfieldFunctionObjects.so")
writeControl timeStep;
writeInterval 1;
log true;

regionType all;
operation minMag;
fields ( U );
}


Similarly, in order to get max value you can define in operation maxMag or max or bananas to get all available fields.


Alternatively, you can use #includeFunc definition in functions dictionary of your controlDict file like:


#includeFunc cellMax


Finally, you can check also under OpenFOAM-9/etc/caseDicts/postProcessing/minMax as well as in OpenFOAM-9/etc/caseDicts/postProcessing/surfaceFieldValue for the definition of each function.


Mind that type volFieldValue will give you min/max values of your volume and not the boundaries, for which I guess you will need to use surfaceFieldValue (but I haven't tested the latter).

This is good. Thanks!
