Who Needs Centrifugal Fan Design Software?
Different teams use centrifugal fan design software for different deliverables, from operating-point selection to CFD optimization and coupled physics verification.
Ventilation engineers sizing fans against duty operating points

It also supports multiphysics couplings so design intent can include heat loads or vibration-sensitive constraints beyond airflow-only verification.
Common Mistakes to Avoid
Common failures come from choosing a tool for the wrong depth of workflow, from expecting selection tools to replace blade-level CFD, or from underestimating the setup effort required by rotating CFD.
Treating fan selection tools as blade-level aerodynamic design suites
Soler & Palau CAD Fan and FläktGroup FanSizer focus on operating-point selection and fan curve alignment, so they are not meant for advanced aero modeling beyond centrifugal fan selection needs. Ansys Fluent and Siemens Simcenter STAR-CCM+ are better choices when blade-channel flow resolution and loss mechanism prediction are required.
Ignoring rotating CFD workflow requirements and convergence realities near stall
Ansys Fluent can face convergence challenges near stall and surge operating points, so setup and validation effort must be planned for rotating passages. Siemens Simcenter STAR-CCM+ also requires expert CFD knowledge and tuning for complex fan cases, so it should be selected for teams ready to manage meshing and boundary conditions carefully.
Using general CAD workflows without centrifugal-fan-specific selection logic
Autodesk Fusion 360 excels at parametric CAD and CAD-to-simulation-to-CAM workflows, but it does not replace the duty-point selection workflows of Soler & Palau CAD Fan or FläktGroup FanSizer. For quick operating-point convergence tied to centrifugal fan curve checks, selection tools like Systemair Fan Calculator are more direct.
Skipping component parameterization when simulation inputs must stay consistent
CAD changes can break CFD input consistency when the impeller and shaft definitions shift, and CADFEM’s Shaft and impeller design tools are built to keep simulation-ready inputs aligned. Without guided parameterization, extra cleanup can be required when outputs need to be made highly customized for CFD.
