Oh, I see, thak you!

One problem I had is that when trying to convert, an exception is raised saying that my coordination number is too low while my domain has a coordination number of 11.75, the math I did was (2*num_bonds)/num_elements (4279 and 728 for num_bonds and num_elements respectivelly)

[PRE-PROCESSING][PlugIn _ConvertElementPairToBeam...]
Trying to compute automatically the coordination nummber value for automatic calibration
Ok, coordination number value is 3.402664e-01
[PRE-PROCESSING][PlugIn _ConvertElementPairToBeam...]
[ERROR]

======================
-- Attached message --
======================
The value of coordination number Cn=0.340266 seems to be false. It is not in the common range of [5, 15]
python: /home/tulio/programs/granoo/tags/2.0/Lib/GranOO/libUtil/Macro.cpp:65: static void GranOO::Util::AssertMsg::RaiseUserAssertion(int, const string&, const string&, const string&): Assertion `0' failed.
Aborted (core dumped)

Is there any way to manually inflate the coordination number or make it read the correct one?

The code I used is right below, also note that the values I'm using for properties are arbitrary.

Anyway, thank you for the help!
