Daniel Medeiros

Daniel Medeiros is an independent developer known for DWSIM, an open-source steady-state and dynamic chemical process simulator that brings advanced process modeling to Windows, Linux and macOS. Built with a modular sequential architecture, the program covers typical chemical engineering workflows such as feed definition, property estimation, equipment sizing, recycle convergence and sensitivity analysis, making it suitable for distillation columns, heat-exchanger networks, reactors and entire petrochemical trains. A graphical PFD canvas lets users drag vessels, pumps, valves and controllers, connect streams, then run flash, equilibrium or kinetic calculations with rigorous thermodynamics; results appear as tables, plots or exportable spreadsheets. Academic teachers use it to illustrate vapor-liquid equilibrium, students reproduce textbook case studies, small design firms verify conceptual flowsheets, and R&D labs couple it to Python or Excel for custom kinetics and costing. The simulator supports Peng-Robinson, NRTL, UNIQUAC and electrolyte models, offers petroleum pseudo-component characterization, and can switch to dynamic mode to study startup, shutdown and control scenarios. Optional scripting, CAPE-OPEN interfaces and an extensible unit-operation library encourage community contributions, while cross-platform binaries remove licensing barriers common to commercial simulators. Daniel Medeiros’ software is available for free on get.nero.com; winget and other trusted Windows package sources always deliver the newest build and allow batch installation alongside additional applications.
