Common Mistakes to Avoid
Common selection mistakes come from choosing a tool that matches geometry drafting but not the performance validation depth, or choosing advanced CFD tools without the setup capacity they require.
Selecting a CAD-only tool for performance validation across a duct network
AutoCAD MEP automates duct drafting with intelligent duct and fitting objects, but it does not position itself as a duct network simulation engine for pressure and airflow behavior. For performance validation, tools like Ventsim Ducting, Fluent by ANSYS, SimScale, or IES VE produce airflow and pressure outputs tied to duct geometry and assumptions.
Underestimating setup and configuration time for simulation-grade models
IES VE and Ventsim Ducting can take time to set up for new duct networks because system configuration and boundary conditions must be defined carefully. Fluent by ANSYS and OpenFOAM require mesh quality and convergence expertise for large or complex duct networks.
Using high-fidelity CFD without a repeatable boundary-condition workflow
SimScale emphasizes boundary-condition workflows for standardized CFD outcomes, which reduces variability across duct revisions. Fluent by ANSYS results depend heavily on turbulence model selection and boundary specification, so boundary choices cannot be treated as afterthoughts.
Assuming routing automation will handle every duct geometry without manual correction
Revit Duct Routing Extensions speeds up standard patterns, but routing behavior depends on properly configured setup and constraints and can lose gains on highly unique routing geometries. Revit MEP routing rules can still require manual modeling workarounds for unusual routing logic.
