| Feb 10, 2016 at 3:10 | comment | added | tpg2114 | This is the topic of my thesis... a rough rule of thumb -- $M < 0.1$ and you are going to suffer accuracy problems with an explicit code; pressure will be under-damped numerically while momentum will be overly damped. This says nothing about efficiency. You will completely get the wrong answer at low Mach numbers and/or face numerical instabilities. | |

| Feb 9, 2016 at 16:42 | comment | added | stali | Which compressible flow solvers (as in low/high mach regimes)? Also, see cs.swan.ac.uk/reports/yr2004/CSR2-2004.pdf | |
