After looking closely at the good and not-so-good parts of the three CFD apps, following is a helpful table to pick the best one for fluid simulations!

SIMULATION APP | W-TUNNEL FREE | AIRFOIL DESIGN | SIMSCALE |
APPLICATION FOCUS | Qualitative Understanding | Inviscid Airfoil Flow | General Purpose CFD |
STRENGTHS | Provides qualitative insights | Specialized in inviscid airfoil flow | Versatile, suitable for various applications |
Simple user interface | Dedicated airfoil analysis | Handles complex simulations with detailed physics | |
WEAKNESS | Limited quantitative data | May not capture viscous effects | Steeper learning curve for beginners, resource-intensive |
Primarily for educational purposes | Limited application due to inviscid focus | Professional-grade simulations | |
Lacks advanced features | Limited accuracy beyond critical points | Requires adequate computational resources | |
PURPOSE | WTunnel Free used for qualitative understanding | Used for initial airfoil design, limited accuracy | Primary tool for comprehensive module development. |
