PAB3D
AS&M developed a three-dimensional multiblock Navier-Stokes code, PAB3D, for propulsion integration and general aerodynamic analysis. It has been used extensively by NASA Langley, General Electric, and other organizations to perform both internal and external flow analysis of complex aircraft configurations. This code was designed to solve the simplified Reynolds Averaged Navier-Stokes equations. A two-equation k-epsilon turbulence model has been used with considerable success, especially for attached flows.

Key capabilities and applications include:
1. Propulsion–Airframe Integration
2. Fluidic Injection Nozzles
3. High Speed Jet Flows
4. Full-Airframe Aerodynamics
5. Integrated Pre-/Post-Processing
​
PAB3D is a robust CFD tool for simulating complex aerodynamic and propulsion interactions. It’s proven across diverse aerospace projects—from nozzle flow to full‑airframe dynamics. Its salient features include: Hybrid Options (URANS/LES, PANS, high‑temperature & compressibility corrections), Parallel Support (Multi-block parallelization across platforms such as Cray, Linux, Mac/Win, etc.), and Pre/Post Software (Unified UPMS GUI for workflow and grid handling).
