Frequently Asked Questions
What is DWSIM?
DWSIM is a computing applications (hpc) application available in the Paramus App Store. Open-source CAPE-OPEN compliant chemical process simulator for steady-state and dynamic simulations. Supports flash calculations (VLE/LLE/VLLE), thermodynamic property packages (Peng-Robinson, SRK, NRTL, UNIQUAC), and unit operations.
Is DWSIM free to use?
Yes. DWSIM is distributed under the GPL-3.0 (Free) license and is available at no cost through the Paramus App Store.
How do I install DWSIM?
DWSIM is installed through Paramus Chemistry OS, an on-premise Windows platform for computational chemistry. Open the Paramus App Store in your local installation and select DWSIM for one-click deployment.
What type of application is DWSIM?
DWSIM belongs to the “Computing Applications (HPC)” category in the Paramus App Store. It runs on Paramus Chemistry OS and can also be accessed through Paramus Cloud for supported workflows.
What platform does DWSIM run on?
DWSIM runs on Paramus Chemistry OS, a Windows-based on-premise platform that provides local compute power for demanding simulations. It requires a Paramus OS installation with appropriate hardware resources.
Can DWSIM be automated or integrated with AI workflows?
Yes. DWSIM is available as part of the Paramus ecosystem which supports MCP (Model Context Protocol) tools for AI-driven automation. This enables integration with large language models and automated research pipelines.
