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

"PSim allows us to spend more time thinking about physics and less time thinking about coding, and it's efficient and easy to use."
