An object-oriented framework that simulates phase morphologies of dense block copolymers melt systems.

psim overview imagePSim quickly solves the numerical self-consistent field theory (SCFT) equations for modeling copolymers.

The SCFT algorithm is rigorous method for coarse-graining models of complex block copolymer mixtures such that sufficient detail is retained to describe the novel morphologies these materials form when they undergo phase segregation. This coarse-graining procedure allows researchers to study block copolymer structure in simulations that can run much faster than more explicit methods such as classical all-atom molecular dynamics.

PSim's built-in three-dimensional visualization capability, multi-platform availability (Linux, Mac OS X, and Windows), and examples will get you up and running quickly.

Examples and documentation (PSim Installation, PSim Quick Start, PSim In Depth, and PSim Reference Manual) for PSim reduce your learning curve and ensure faster results.

"PSim allows us to spend more time thinking about physics and less time thinking about coding, and it's efficient and easy to use."
– Professor Lisa M. Hall, Ohio State University

Copolymers in a Cylindrical Pore

Simulation from the self-consistent field theory (SCFT) code PSim. This simulation shows the effects of confinement on the phase-segregated morphologies for diblock copolymers.
