Name	Type	Def	CR Name	Description
bakdif	Float	bakdif_out	bakdif	Spatial implicitness parameter. Any value greater than 0 adds numerical dissipation (usually necessary). bakdif=0 is 2cd-order space-centered, bakdif=1.0 is fully upwinded. Recommended value for electrostatic runs: 0.05. For electromagnetic runs, bakdif should be 0.
bd_exp	Integer	bd_exp_out	bd_exp
fexpi	Float	aimag(fexp_out)	fexpi
fexpr	Float	real(fexp_out)	fexpr	Temporal implicitness parameter. Any value smaller than 0.5 adds numerical dissipation. fexpr=0.5 is 2cd order time-centered, fexpr=0 is fully implicit backward Euler, fexpr=1.0 is fully explicit forward Euler. Recommended value: 0.48
