Constraint Preserving AFD-WENO Schemes for Relativistic Hydrodynamics with General Equations of State
Pramodit Mishra, Shubham Upadhyay, Rakesh Kumar +1
We develop a high-order physical-constraint-preserving (PCP) alternative finite difference weighted essentially non-oscillatory (AFD-WENO) scheme for the special relativistic hydro…

Riemann invariant-based alternative WENO scheme for a two-layer thin film model
Biswarup Biswas, Rahul Barthwal, Rakesh Kumar
In this article, we develop a multi-dimensional two-layer thin film model extending the thin film model proposed in \cite{barthwal2025hyperbolic}. The model considered in \cite{bar…
