Common Mistakes to Avoid
Several repeatable pitfalls show up across wind modelling tools when project expectations do not align with model assumptions, workflow demands, or output framing.
Using a high-fidelity CFD tool when steady-state microscale resource mapping is the decision bottleneck
Teams often choose ANSYS Fluent or STAR-CCM+ when a project primarily needs steady-state microscale resource assessment and siting support. WAsP is designed for validated microscale wind predictions and Wind Atlas extrapolation, which avoids over-investing in unsteady CFD where it does not change the siting decision.
Skipping uncertainty framing for energy yield decisions
Relying on single-point outputs can weaken feasibility conclusions when atmospheric variability is material. WindPRO’s integrated uncertainty analysis and probabilistic forecasting are built to address this risk in energy yield prediction workflows.
Underestimating meshing time and geometry churn for turbine and terrain models
Manual meshing bottlenecks can derail project timelines when there are repeated turbine layout changes. STAR-CCM+ polyhedral meshing with surface wrapping supports rapid high-quality grid generation for intricate terrain and turbine geometries.
Expecting research-grade customization from a tool with limited extensibility or GUI
