Robert Caulk proposed the following answer:
Hello Luc,

I ran your script 10 times with each of useSolver=0 and 3 (also 4 to
check the GPU consistency). I was unable to reproduce the failure you
describe, I simply get the following results 100% of the time:

Qin= -4.12495019931  Qout= 4.12493778356  ARE THEY EQUAL? IF NOT-> NO FLOW!
Permeability [m2]= 0.0041254746407  || Hydraulic conductivity [m/s]= 40512.1609716

I am running Yade from sources (git version as of Sep 28, 2017, which is
the latest w.r.t basic FlowEngine and FlowBoundingSphere) on Ubuntu
16.04 LTS.

If I were you, I would clean my build directory and re make/install.

Best,

Robert
