This project provides an object-oriented software package for dynamic flux-balance analysis (DFBA) simulations using implementations of the direct method or Algorithm 1 described in the paper Harwood et al., 2016. The main algorithms for solving embedded LP problems are written in C++ and use the GNU Linear Programming Kit (GLPK) and the Suite of Nonlinear and Differential/Algebraic Equation Solvers (SUNDIALS) CVODE or IDA. Extension modules to cobrapy are provided for easy generation and simulation of DFBA models.
