Polymatic: A Simulated Polymerization Algorithm
13 Mar 2013 | | Contributor(s):: Lauren Abbott, Coray Colina
Polymatic is a set of codes for structure generation of amorphous polymers by a simulated polymerization algorithm. The main task of Polymatic is to perform polymerization steps within a system based on a number of defined bonding criteria. It works in conjunction with a simulation package to...
Can I request for multiple nodes when running LAMMPS on Nanohub?
The LAMMPS tool on Nanohub has two features – atomic slip stick simulator and polymer modeler. Is there a way to perform simulations on LAMMPS other than the above on NANOHUB....
