We present numerical methods to solve the Israel-Stewart (IS) equations of causal relativistic dissipative fluid dynamics with bulk and shear viscosities. We then test these methods studying the Riemann problem in (1+1)-- and (2+1)-dimensional geometry. The numerical schemes investigated here are applicable to realistic (3+1)--dimensional modeling of a relativistic dissipative fluid.

Discussion (0). Continue with ORCID to comment.

  1. Relativistic Dispersion Spectra across Lorentz boosted frames: Spurious modes and the enigma of causality

    hep-th 2025-12 conditional novelty 5.0 of 10

    Rest-frame dispersion modes can be mapped into Lorentz-boosted frames through a parametric re-parametrization; the boost-generated 'spurious' roots appear exactly when the mode count is not conserved, which the author...

  2. Mapping Sparse Triangular Solves to GPUs via Fine-grained Domain Decomposition

    cs.PF 2025-08 unverdicted novelty 5.0 of 10

    A domain-decomposition scheme sizes subdomains to GPU shared memory to remove synchronization from sparse triangular solves, reporting 10.7x and 3.2x speedups for triangular solves and ILU0-BiCGSTAB on the AMD MI210.
