Simulation-independent parameters

Simulation-independent parameters, as the name implies, do not depend (or only weakly depend) on a given simulation. As such, they have been set by default to optimal values for the vast majority of simulations and only advanced users should modify them.

An example of simulation-independent parameters are those defining convolution perfectly matched layers, specifically CPML_fsigmaopt ($\sigma_\text{opt}$), CPML_kappamax ($\kappa_\text{max}$), CPML_alphamax ($\alpha_\text{max}$), CPML_m ($m$), and CPML_ma ($m_\alpha$). These have already been set to the optimal values 1.1, 13.5, 0.225, 3.5, and 2[1].
