abstract = {<p style="text-align: justify;">In this paper, we further extend the derivative-based finite-volume multi-resolution Hermite weighted essentially non-oscillatory (MR-HWENO) scheme proposed in our previous article (Li, Shu and Qiu, J. Comput. Phys., 446:110653, 2021) to
simulate the steady-state problem. When dealing with the steady-state problem, the
process of updating and reconstructing the function values is similar to the previous
scheme, but the treatment of the derivative values is changed. To be more specific, instead of evolving in time, in the sense of cell averages, the scheme uses the derivative
at the current time step and the function at the next time step to reconstruct the derivative at the next time step by direct linear interpolation. There are two advantages for
this approach: the first is its high efficiency, when handling the derivative, neither the
update on time nor the calculation of nonlinear weights is required; in the meantime,
the CFL number can still be taken up to 0.6 as in the original scheme; the second is
its strong convergence, the corresponding average residual can quickly converge to
machine accuracy, thus obtaining the desired steady-state solution. One- and two-dimensional numerical experiments are given to verify the high efficiency and strong
convergence of the proposed MR-HWENO scheme for the steady-state problems.</p>},
