divergence_correction for basic solver variants has now 3 possibilities: 

0: uncorrected, slope per sidelength (physical dimension) e = res/dim
1: corrected by sidelength, slope per unitlength          e = res/1
2: corrected such that distance between FPs               e = 1

alway regarding the medium length of x,y,z direction
