Implicit dual time-stepping positivity-preserving entropy-stable schemes for the compressible Navier-Stokes equations
Mohammed Sayyari, Nail K. Yamaleev
We generalize the explicit high-order positivity-preserving entropy stable spectral collocation schemes developed in Upperman 2023 and Yamaleev 2023 for the three-dimensional (3D)…

A Combined Parallel-in-time Direct Inverse (ParaDIn)-Parareal Method for Nonlinear Differential Equations
Subhash Paudel, Nail K. Yamaleev
As has been shown in our previous work, the parallel-in-time direct inverse (ParaDIn) method introduced by Yamaleev and Paudel in (arXiv: 2406.00878v1, 2024) imposes some constrain…

A New Parallel-in-time Direct Inverse Method for Nonlinear Differential Equations
Nail K. Yamaleev, Subhash Paudel
We present a new approach to parallelization of the first-order backward difference discretization (BDF1) of the time derivative in partial differential equations, such as the nonl…
