Ff2d | V.2.21

: Fine-grained control over inlet velocities, pressure outlets, and wall friction. Visualization and Post-Processing Contour and Vector Plots

: Support for structured or unstructured 2D grids, often with adaptive mesh refinement (AMR) to increase resolution in areas of high gradient (e.g., around airfoils or pipe bends). Analytical Features Steady-State and Transient Solvers ff2d v.2.21

) or a different niche utility, please provide a bit more context so I can narrow down the exact feature list for v.2.21. system requirements for this specific version? : Fine-grained control over inlet velocities

: Visualizing pressure distributions, velocity fields, and temperature gradients. Streamline Tracking generally refers to Finite Flow 2D

Based on available technical and software documentation, generally refers to Finite Flow 2D
