 nlsop TODO
 ----------
 
-IMPORTANT:
+allgemein:
 - durchdenke/checke diffusion
 
-- continue funktion / (naechster punkt)
-- start mit anfangsbedingungen (beschreibung aus file)
-- opengl visualisierung
-
-parameter:
-- b_ap=0, a_ap klein, s gross
-- abschaetzung einiger physikalischer groessen
-- z kleiner, anpassung durch steigung/y-abschnitt von c(C) & nukl. BK
-
 fragen:
-- diffusion innerhalb amorphen?
-- diffusionssaettigung eineramorphen zelle?
-- diffusion in z (nur von cryst ins amorphe)?
-
+- diffusionssaettigung einer amorphen zelle?
