London, UK Creative Fields, a provider of the state-of-the-art CFD meshing software, is proud to announce that the turbulent flow simulation around the DrivAer vehicle was solved successfully using CF-MESH+ in combination with OpenFOAM. CF-MESH+ is a fully automated and easy-to-use CFD meshing software solution that features superior capabilities for mesh generation in arbitrary complex geometries.
The generic DrivAer model for external flow was introduced in 2011 to narrow the gap between the overly-simplified models commonly used in automotive aerodynamics investigations (e.g. Ahmed body) and the highly complex production cars. CF-MESH+ was used to automatically generate a volume mesh around the DrivAer vehicle from a few simple specifications. The volume mesh was then successfully used in turbulent flow simulation around the vehicle by using OpenFOAM.
“We are proud of yet another successful case where CF-MESH+ has proven an excellent companion to OpenFOAM when it comes to automotive aerodynamics. Advanced boundary layer generation capabilities and the ability to control the layer thickness in the first cell near the wall make CF-MESH+ an ideal candidate for mesh generation in external aerodynamics simulations.” said Mario Baburic, Managing Director at Creative Fields.
The process of automatically generating a suitable mesh for automotive turbulent flow simulation was straightforward.
The automatically generated mesh has no sudden cell size change, instead every cell size change is resolved gradually, regardless of its position (further from the car geometry or in the boundary layer), which has a positive impact on the stability of the calculation and its convergence.
