 IMPORTANT:
-- ueberpruefe b_ap=0 verhalten
-- ueberpruefe code generell !!
 - durchdenke/checke diffusion
 
-- p(cryst->amorph)~druckspannung~c(C) in amorphen gebiet
 - start mit anfangsbedingungen (beschreibung aus file)
 - dfb optional (cluster mode)
-- -C: convert binary savrfile to gnuplot file
