The proposed effort will provide a robust and automated approach for creating body-conforming meshes suitable for WMLES simulations for arbitrary geometries in a MPI parallel environment. Most current commercial mesh generation software operates on engineering workstations and usually takes advantage of multiple core processors to accelerate the mesh generation process. The proposed effort would work on multi-core workstations and in a distributed parallel environment to take advantage of more processors and much more memory to create large scale meshes for WMLES simulations. The developed framework will also provide a pathway to implement solution-based adaptive mesh refinement during the analysis phase that could operate simultaneously with the CFD analysis tools.
NASA has developed numerous simulation tools for WMLES with application in air vehicles (both fixed and rotating wing), space vehicle launch, assent, and entry, parachute deployment, and complex moving-body problems. The proposed technology will be applicable to these program objectives and support existing simulation workflows.
Military applications include vehicle aerodynamics and store separation. Civil applications include vehicle aerodynamics, propulsion integration, rotorcraft, medical device, power generation, and complex moving-body problems.
