## Timestep and Cost Analysis of Pressure- and Density-Based Methods

Jupyter Notebook here: https://git.io/fjRjL PDF Article here: http://dx.doi.org/10.13140/RG.2.2.17472.58886 For an explicit compressible algorithm the maximum timestep one can take is dictated by both the advective and acoustic speeds in the flow. This is given by the famous CFL condition $$V \frac{\delta t}{\Delta x} \leq 1$$ where $V$ is the maximum speed in the …
