## Description

DWSIM is a powerful, offline chemical process simulator designed for Android devices. It features a touch-enabled Process Flowsheet Diagram (PFD) interface that allows engineers to quickly build complex chemical process models. With support for advanced thermodynamic calculations including VLE, VLLE, and SVLE using various equations of state and activity coefficient models, DWSIM enables precise simulation of fluid properties and phase distributions.

The simulator includes a comprehensive compound database of over 1200 chemicals and rigorous thermodynamic models such as PC-SAFT, GERG-2008, Peng-Robinson, and others. Users can simulate unit operations like mixers, separators, reactors, pumps, and heat exchangers. Additional capabilities include petroleum characterization, parametric studies, optimization tools, and support for chemical reactions. Its fast, multicore CPU calculation engine processes simulations efficiently, while results can be saved, loaded, or exported as PDF and text. Some premium features are available via one-time in-app purchases.

## Review summary

DWSIM is a powerful and useful chemical process simulation app, especially praised by students and professionals for its comprehensive features on mobile devices. However, users frequently mention difficulties adding new compounds from databases, limited free version features, and some interface/input issues like missing keyboards and malfunctioning modules. Despite these drawbacks, its ability to save results and compatibility with desktop versions make it a valuable educational and professional resource.

### Pros

- Very powerful and comprehensive chemical process simulation tool for mobile devices.
- Highly useful for chemical engineering students and professionals for learning and process simulation.
- Allows manual input of chemical data and has a fairly complete chemical compound list.
- Enables saving results as text or PDF, which is useful for academic and professional purposes.
- Cross-platform compatibility and ease of use enhance productivity, especially for on-the-go simulations.

### Cons

- Difficulty adding new compounds from online databases using CAS ID, limiting simulation scope.
- Many advanced features and property packages are locked behind a paywall, affecting free version usability.
- Issues with input interfaces like pipe segment editing where necessary keyboards or input dialogs don't appear.
- Some functionality issues with tools like sensitivity analysis and reactor modules not working as expected.
- App instability when used offline, leading to crashes and forced stops after updates.
