Fluid Systems Design

Dassault Systèmes (DS)' Fluid Systems Design solution provides a full complement of traditional piping and HVAC design functions. System diagrams provide logical process definitions and convey specifications for both piping and HVAC routing. The software allows users to define connections across disciplines. These connections can be analyzed and tracked within the PLM environment, which facilitates tracking of design modifications.

Moving from the basic design, where the main layout is decided, the solution allows the re-use of the zone-split schema. Originally defined for plant structure breakdown, the zone schema is used at this stage to decide how piping and other system should be spooled, which improves construction planning by associating system components and BOMs with particular zones of the plant.

Because the basic design is organized in a single view of zone assemblies, detailing is highly automated and takes advantage of the knowledge defined and saved in the specification catalogs. In addition, logical diagrams and design ruleshelp automate parts placement and catalog component selection. This allows designers to spend more time on optimal layouts and reuse practices proven successful on previous projects.


Detailed design activities are actually preparation for construction because critical manufacturing data for pipe bending and flanging is being captured. DS PLM can also interface with standard isometric diagramming applications, like ISOGEN from Alias. All plant process systems follow the same logical breakdown structure as the plant’s structural zone plan. This benefits users because final plant construction sequences that apply to the zone also apply to process systems. More detailed processes, such as pipe bend simulation, can be conducted to verify whether a given spool can be manufactured or whether adjustment are required before part manufacturing will become practical.

Plant Fluid Systems Design solution includes:

  • Piping and instrumentation diagram (P&ID)
  • HVAC diagrams
  • 3D functional design
  • Piping detailed design
  • Piping manufacturing extraction (spool drawing)
  • HVAC detailed design
  • HVAC manufacturing drawing extraction
  • Support and hangers design


CATIA models provide exact cut lengths, isometric and fabrication details. Since we give suppliers detailed drawings, they have less liability from potential errors. We have been able to reduce our supplier costs by up to 30%.
