Predicting Lift and Drag for Aerodynamic Bodies with SOLIDWORKS Flow Simulation

Подробнее о видео

Learn how to quickly predict lift and drag forces on aerodynamic bodies using SOLIDWORKS Flow Simulation. Considerations are discussed for ground and air vehicles including sizing of computational domain, and mesh refinement techniques such as equidistant mesh. Basic results extraction is also covered including numerical values and color plots indicating laminar/turbulent regions. This video is a "getting started" or introduction level of detail.

For a deeper dive into these topics, consider the two pre-recorded webinars below: Predicting Lift and Drag in SOLIDWORKS Flow Simulation -
Covers method of using parametric study to pre-position aircraft at various angle of attack and flow rates and iteratively solve for lift and drag curves. SIMULIA xFlow is also demonstrated for analysis of detailed turbulence.

The Virtual Wind Tunnel in SOLIDWORKS Flow Simulation
Covers varying angle of attack using dependencies in a transient analysis as well as how to define equation goals to properly calculate lift and drag values, as well as L/D ratio and managing a design change.
