flameindex3

algorithm

calculates (Takeno) flame index to distinguish between premixed and non-premixed type of flame
for pos. index flame is of premixed type;
for neg. index flame is of non-premixed type;
optionally plots flame index along flamefront;
optionally plots histogram of flameindex along flame front

[inn,variso]=flameindex3(X,Y,Z,Y_H2,Y_O2,fdefine,level,s)

[inn,variso]=flameindex3(X,Y,Z,Y_H2_,Y_O2_,Y_OH,0.5,'rel')

X,Y,Z	vectors defining the rectangular domain necessary input arguments
Y_H2,Y_O2	mass fractions of H2 and O2 necessary input arguments
fdefine	variable defining the flame front optional input argument, necessary only for the plot
level	isovalue of fdefine defining the flame front optional input argument, necessary only for the plot
s	switch, s='abs' for absolut values of level s='rel' for relativ values of level optional input argument, necessary only for the plot

inn	matrix of normalized flame index
plots	flame index along flame front; histogram of flame index along flame front optional outputs
