CFDRC proposes to develop a DoD open source geometry kernel and associated APIs that can be incorporated into DoD High-Performance Computing frameworks to enable dynamic simulations of a) surface deformation or relative motion encountered in 6DOF motion of control surfaces, moving rotors in turbomachinery, store separation, and aeroelasticity; b) adaptive mesh refinement near curved boundaries; and c) use of high-order CFD solvers with curved elements. Phase I will focus on the development of a geometry kernel for improving the original linear surface mesh using three modern technologies: 1) high-order analytical NURBS fitting; 2) Bzier surface fitting, and 3)modern subdivision surfaces, which has been widely used in computer animation and video games. The Phase I effort also includes curved surface element generation using the high-order NURBS analytical surface; coupling to the volumetric mesh deformation to improve the quality of curved meshes; and demonstrations for the problems of a) moving body, b) aeroelasticity and c) high-order element generation. Phase II will establish a versatile set of APIs comprising a well-developed geometry kernel to efficiently perform commonly required tasks related to geometry and associated computational meshes, and the source code will be provided for incorporation into larger DoD developed tools and frameworks.
