Unfortunately I know very very few python, so I do not know how to do
this in this framework. With C++ instructions, (inside the code) it is
like that
dynamic_cast<Force*>(*Metabody-*>physicalActions->find(*id_facet*,actionForce->getClassIndex())
. get() )->force;
(I see clearly what can be the advantages of python by writing this...)
An intermediate mean for you is (until someone can answer you more
precisely) to add an Engine "ForceRecorder" (source in
pkg/dem/Engine/StandAloneEngine/), defined with the id of the facet, to
o.engines. This will store the force you want in an output file you can
later analyse with the software you want.

How can I get forces affected on 1 facet from spheres: I need it for plot?
Thank you
PS I promise, that I will place all answers to instructions or FAQ.

You have to use TranslationEngine and subscribe facets to it.
That's what I do. See e.g. scripts/test/Dem3DofGeom.py for an
example. The sphere is moved that way. Facet ids are returned
by O.bodies.append.
ids=O.bodies.append([utils.facet(...),utils.facet(...)])
print ids ## [0,1,2,3,4]
O.engines=[...,TranslationEngine(subscribedBodies=ids,translationAxis=[0,0,1],velocity=1),...]
