A new class of high-order summation by parts finite-difference schemes
Leonid Dovgilovich, Rustem Maksyutov, Ivan Sofronov
We develop summation by parts (SBP) approach for generating high-order finite-difference schemes on the interval and propose new sets of schemes up to the 12th order. The coefficie…

High-accuracy finite-difference schemes for solving elastodynamic problems in curvilinear coordinates within multiblock approach
Leonid Dovgilovich, Ivan Sofronov
We propose highly accurate finite-difference schemes for simulating wave propagation problems described by linear second-order hyperbolic equations. The schemes are based on the su…
