I am in search of commercial Computational Fluid Dynamics (CFD) software tailored for modeling hydraulic structures, particularly for applications related to stormwater, small dams, flood control structures, channels, and similar scenarios. The primary focus will be on studying free-surface flows. Affordability is a crucial consideration in the selection process. While I am already familiar with Flow-3D, Ansys Fluent, and Ansys CFX, I am open to exploring additional software options. I would appreciate any recommendations for alternative applications, and it would be beneficial to receive insights on various features to facilitate a comprehensive comparison for making an informed decision.
