[Paper Review] MSTACS with Slope 3 Blew Up After 255 Steps at Co=0.5 — Compressive Differencing and the Courant Limit
·6 min read
We ran the compressive scheme of MSTACS eq. (18) on a 1D slab. Without redistribution it diverges above Co=0.44. The culprit is the product of the NVD slope k and the Courant number.

Raising artificial sound speed from 5 to 15 cuts the stable step by three. OS-MSTACS lists a volume error E_G of 6.57e-8, four orders under OS-CICSAM.
