DWSIM - A Chemical Process Simulator
DWSIM is an open source chemical engineering process simulator. DWSIM compares well with the capabilities of commercial simulation packages. DWSIM has been built on .NET and DWSIM runs on Windows, Linux and Mac OS X. DWSIM is CAPE-OPEN compliant and has an excellent thermodynamic package.
DWSIM has several unit operations such as - Mixer, Splitter, Separator, Pump, Compressor, Expander, Heater, Cooler, Valve, Pipe Segment, Shortcut Column, Heat Exchangers, Reactors, Component Separator, Orifice Plate, Distillation/Absorption Columns, Solids Separator and Cake Filter. One can combine the above unit operations to simulate many a chemical plants.
When compared to results from any proven commercial software DWSIM gives identical results. Results given by DWSIM also match with actual plant results.
DWSIM has a sequential modular approach, that is inputs have to be given and outputs are calculated. An utility called 'ADJUST' can be used where trial and error approach can be used to calculate input values. DWSIM an use ADJUST to solve design problems too.
DWSIM comes with excellent graph plotting capabilities which can check if thermodynamic package is appropriate. DWSIM can be used to custom build an unit operation, thus overcoming absence of specialized modules.
