DexaSIM

What is DexaSIM?

DexaSIM represents the most advanced and efficient software tool for performing complete research and development work on exhaust gas after treatment systems.
The user-friendly simulation package for analysis and design is comfortable to use, even for non-CFD engineers.
The software consists of a Graphical User Interface ( GUI), which provides simple and effective tools to quickly model and simulate any pipeline system.
The Open Source Computational Fluid Dynamics (CFD) flow solver OpenFOAM is embedded in the software.

Who can use DexaSIM?

The flexibility of DexaSIM makes the software applicable to practically any industrial process that involves porous media, flow through pipeline systems and chemical reactors. Basically, the software can be used for any gas purification system, however, its flexibility allows it to be used in a lot more industrial and environmental processes. Some applications are:

• Superior virtual material design based on novel strategies
• Virtual sensor design based on multicomponent gas diffusion models
• Industries such as chemical engineering, automotive and waste incineration

DexaSIM is prepared for the future! It is able to conduct exhaust gas after treatment system design including the dynamic simulation of soot deposition and filter regeneration according to the Euro 4 and beyond.
