Design In the development phase different
Dinex uses SolidWorks - a 3D CAD methods of calculation are applied,
system programme, which is a major based on theoretical values and
advantage when communicating with experience, as well as information
customers as exchanging 3D models supplied by customers, such as:
and drawings etc. is simplified. • Engine type
• Engine power
2D Drawings • Exhaust temperature
• Portable Document Format (PDF) • Exhaust flow
• 2D DXF/DWG (.DXF, .DWG) • Space envelope available
• TIF image (.TIF)
Calculations are supported by a CFD
analysis using a Comsol Multiphysics
system programme, which verifies the
design of silencers. All new designs are
tested to ensure theory and real-life
always matches up.
