Aerodynamic studies are a critical part of airplane design
Aerodynamics is a key aspect in the design of any aircraft or spacecraft, be it commercial, military, UAV’s, rotorcraft or space shuttles.
  • STAR-CCM+ is unrivaled in its ability to quickly and efficiently tackle complex geometries. Shown here are surface pressures on an Airbus A380 with flaps deployed and landing gear modeled. Streamlines visualize the flow pattern in the wake of the aircraft.

Aerodynamic design is the key to meeting the stringent performance requirements during vehicle design like efficiency, speed, maneuverability, range and acoustics.

In addition to effectively predicting the aerodynamic characteristics of any vehicle, simulation also aids in effectively optimizing the design for peak performance, while reducing design costs and delivering the aerodynamic design quickly.

CD-adapco’s flagship code, STAR-CCM+, is a Navier Stokes solver that has been extensively validated for aerodynamic applications. STAR-CCM+ offers not just a CFD solution but an entire engineering process for aerodynamicists, allowing them to accurately and efficiently utilize their time in analyzing different designs and their aerodynamic characteristics.

Common application of STAR-CCM+ includes aerodynamic optimization, lift/drag prediction, stability & control, aero loads generation, engine airframe integration, fairing design and aeroelastic calculations.

Application areas within aerodynamics include:

  • Subsonic, Transonic, Hypersonic, Supersonic
  • Aeroacoustics
  • Store release & weapons bay analysis
  • Aircraft, missile, launch/reentry vechile aerodynamics
  • High lift devices
  • Store/Stage separation
  • Aeroelasticity

STAR-CCM+ in aerodynamics:


STAR-CCM+ is well validated in various application areas of aerodynamics, both by CD-adapco and our customers, thereby allowing users to accurately simulate various aerodynamic problems and phenomena. Accuracy is of paramount importance in aerodynamic calculations and STAR-CCM+ is well validated in the following areas (More validation information under Resource Center): high-lift devices, drag prediction, transonic drag rise, transonic shocks, boosters, missiles, hypersonic, nozzles in crossflow, impinging jets and transonic airfoils.

CD-adapco has participated in the industry-standard AIAA high-lift and drag prediction workshops to validate the accuracy of STAR-CCM+ in these areas. More information about workshop results and other validation by our customers are available in the case studies section.

Easy-to-use, automated meshing

STAR-CCM+ enables rapid turnaround of complex geometry through a streamlines, automated mesh generation process. Key meshing features like Surface Wrapping of "dirty" CAD, CAD embedded client, Automated Polyhedral Volume Meshing, Automated Prism Layer Generation and Advancing Layer Mesh offer a host of meshing options for the user to effectively turnaround any complex geometry for analysis in a quick time.

Overset Mesh, the latest STAR-CCM+ capability, allows effective simulation of complex moving objects, by generating an individual mesh around different moving components, that can move around in a background mesh. More information can be found on our meshing capabilities under the Technologies section.

Efficient solver technology

STAR-CCM+ offers both Pressure Based (Segregated) and Density Based (Coupled) solvers with 2nd order discretization. Pre-conditioning and Algebraic Multi-Grid Acceleration (AMG) techniques offer stability and control of solutions. A complete set of turbulence models are available, ranging from popular model like K-Epsilon, K-Omega, Spalart-Allmaras, Reynolds Stress Transport (RST) and Subgrid scale models to advanced models like Gamma-Re-Theta Transition Modeling.
