Mixed-precision GPU algorithms for efficient turbulent flow simulations with Raviart-Thomas finite elements
A solution framework with fast matrix-free operator evaluation for all ingredients, combined with multigrid solvers for the Poisson problem, and a robust mixed-precision algorithmic framework to generate accurate initial guesses for the iterative linear solvers are developed.
