DWSIM is an open-source chemical process simulator for students, chemical engineers and chemists. Its graphical flowsheet editor connects material streams to equipment such as pumps, heat exchangers, reactors and distillation columns. Thermodynamic models calculate properties and phase behavior, while built-in tools support sensitivity analysis, optimization, petroleum characterization and compound creation.

DWSIM is an open-source chemical process simulator for chemical engineering students, engineers and chemists. It models process flowsheets using thermodynamic property methods and unit-operation models, helping users study how materials and equipment behave together. Its graphical interface represents a process as a connected schematic of streams and equipment, with editable parameters for each item and automatic error detection to help identify issues in a simulation.
Users can build flowsheets from unit operations such as mixers, splitters, separators, pumps, compressors, expanders, heaters, coolers, valves, pipes, heat exchangers, reactors and distillation equipment. Material streams connect these operations, allowing users to follow calculated process conditions through the system. Available reactor models include conversion, equilibrium, plug-flow and continuous stirred-tank reactors; column models include shortcut distillation and several absorber configurations. The simulator includes thermodynamic methods such as Peng-Robinson, Soave-Redlich-Kwong, NRTL, UNIQUAC and UNIFAC for calculating properties and phase behavior.
Additional utilities support phase-envelope and hydrate calculations, pure-component property checks, critical-point calculations, pressure-relief valve sizing and vessel sizing. Petroleum workflows include characterization from C7+ fractions or distillation curves, generation of distillation curves and petroleum cold-flow property calculations. Users can also create hypothetical or custom compounds, manage reactions, and work with an integrated spreadsheet. These tools extend a flowsheet beyond standard equipment calculations and help prepare data for more specialized studies.
For comparing process behavior, DWSIM provides sensitivity analysis and a multivariate optimizer with bound constraints. Data regression for binary compounds can be carried out with different thermodynamic models and methods, with results presented as graphs that can be exported to other applications. Flowsheet schematics can be copied to the clipboard as images, making it easier to include process diagrams in reports or related documents.
DWSIM is available as open-source software at no cost, and its source code can be examined by users who want to understand or adapt its calculations. The supplied platform information includes Windows 10; the program is also identified as available for Linux and macOS. Its range of models makes it useful for coursework, process studies, thermodynamic analysis and preliminary equipment calculations.
