Hi all,

I'd like to know the effect of SummationByParts when it is activated. If it's activated, does it touch by default some finite-differencing scheme? For example, In qc0-mclachlan.par, SummationByParts is activated with 4th order, does it mean all 1st derivatives are replaced with SBP? Or in SBP in qc0 does nothing because it's never been inherited by other thorns?

Cheers,

Hee Il
