USER-MESONT is a LAMMPS package for simulation of nanomechanics of carbon 
nanotubes (CNTs). The model is based on a coarse-grained representation 
of CNTs as "flexible cylinders" consisting of a variable number of 
segments. Internal interactions within a CNT and the van der Waals 
interaction between the tubes are described by a mesoscopic force 
field designed and parameterized based on the results of atomic-level 
molecular dynamics simulations. The description of the force field 
is provided in the papers listed below.

This folder contains a Fortran library implementing basic level functions 
describing stretching, bending, and intertube components of the CNT tubular 
potential model (TPM) mesoscopic force field.

This library was created by Alexey N. Volkov, University of Alabama, 
avolkov1@ua.edu.
