Complexity of computational fluid dynamics (CFD) problems has increased tremendously in terms of physics-based models, multiscale mathematics, robust solvers as well as complex geometries applicable to almost all application domains. In order address such challenging multi-scale, multi-physics interdisciplinary CFD problems, a collaborative and integrative problem solving environment (PSE) is needed that could utilize the state-of-the-art high performance computing (HPC) platforms without deteriorating in performance and compromising on the deliverables. The CFD Toolkit is an on-going research initiative at the Center for Computation and Technology (CCT), LSU to tackle these aforementioned issues:

• A collaborative and cyberinfrastructure enabled PSE for grand challenge fluid flow and transport problems.

• A computational tool that scales and adapts well on almost all state-of-the-art as well as future HPC platforms.

• An integrative interdisciplinary tool that addresses the research as well as the teaching needs for a variety of disciplines in a seamless manner.

Various application drivers for the CFD Toolkit are from the areas of biomedical, engineering, environmental, coastal as well astrophysical disciplines utilizing a wide range of numerical schemes as well as computational domain discretizations. A variety of numerical solvers (PETSc, Trilinos) already interface with the cactus framework and can be used to exploit the advantages and avoid the limitations of any specific numerical solver. Currently, the CFD Toolkit supports the finite difference numerical schemes for the incompressible Navier-Stokes on a variety of structured meshes.
