Software developed in the PSEL include

• DAEPACK, a software library for general numerical calculations,
• DFBSIM, a FORTRAN numerical integration scheme for large-scale systems of differential equations encountered in dynamic flux balance analysis.
• CompGraph, a C++ utility for generating computational graphs of factorable functions.
• DFBAlab, a MATLAB tool for dynamic flux balance analysis with capabilities for dealing with non-unique LP solutions and infeasible LPs.
• DSL48S, a suite of subroutines for the numerical solution of large-scale sparse initial values problems in differential-algebraic equations and their related sensitivity systems,
• GDOC, a software library for global optimization of problems with ordinary differential equations (ODEs) embedded,
• Jacobian, an equation-oriented simulator for dynamic models,
• PSD Bounding Tools, a collection of MATLAB-based codes for calculating bounds on various descriptions of a particle size distribution (PSD) given only finitely many of its moments,
• libMC, a software library for calculating convex/concave relaxations of factorable functions as well as subgradients of these relaxations.
