Automated Gridding and Flow Solver

Cart3D tutorials & related documentation

Cart3D is a high-fidelity inviscid aerodynamics analysis package that allows users to perform automated CFD analysis on arbitrarily complex geometry, often within minutes. The package includes utilities for geometry import and intersection, mesh generation, flow simulation, and post-processing of results. The main flow solver runs in parallel (OpenMP) with excellent scalability. The ease of handling geometries makes Cart3D a useful tool alongside other CFD programs.

  • Cart3D is highly effective for supersonic and hypersonic flow simulations
  • Calculate aerodynamic loads like CL and CD, perform sonic boom predictions, and compute wave drag analyses.
  • Users can easily generate aero databases from hundreds or thousands batch-processed cases to characterize flight envelopes or the design spaces.
  • Users can easily setup an optimization framework using RAGE, Cart3D, and their choice optimizer.
  • Cart3D is a sufficient and higher-fidelity substitute for panel codes would have been used

What is Adjoint Meshing?

Back to top

The Adjoint Method is the quickest way to build a robust mesh for arbitrary complex geometries. Cart3D+Adjoint generates a computational mesh that minimizes errors in a user-defined objective function, such as lift or drag. The tool enables users who don’t have subject matter expertise in CFD to easily create a quality mesh. It also offers experienced analysts a powerful way to characterize the flow field by automatically capturing areas of interest. Users can spend more time engineering, and less time on mesh generation. Check out our case study in the brochures section.
