On the measurements of numerical viscosity and resistivity in Eulerian MHD codes

Tomasz Rembiasz, Martin Obergaulinger, Pablo Cerdá-Durán +2

We propose a simple ansatz for estimating the value of the numerical resistivity and the numerical viscosity of any Eulerian MHD code. We test this ansatz with the help of simulati…
