lincut

algorithm

draws linear cut normal to flame front between user defined boundaries
and extracts a 1d profile from the 2d field of a user defined variable along the cut
plots the cut and variable extracted along the cut

[XMIN,XMAX,YMIN,YMAX,XX1,YY1,VV1,VV2,VVG]=lincut(X,Y,XS,YS,NXS,NYS,fdefine,variable,dl,level,s,iso1,iso2)

[XMIN,XMAX,YMIN,YMAX,XX1,YY1,VV1,VV2,VVG]=lincut(X,Y,0.0052,0.0044,-0.7627,0.6468,Z,temperature,0.00005,0.5,'abs',0.9,0.1)

Name	description
X,Y	vectors defining the rectangular domain
XS,YS	coordinates of starting point of the cut
NXS,NYS	components of normal vector defining the direction of the cut
dl	steps between two iterations
fdefine	variable defining the flame front
variable	variable to be extracted along the cut
level	isovalue of fdefine defining the flame front
s	switch (choose level, iso1,iso2 is rel. or absolut)
iso1, iso2	isolevels defining boundaries of flame front (e.g. 0.9, 0.1)

Name	description
XMIN,XMAX,YMIN,YMAX	coordinates of intersection cut and boundaries of flame front
XX1,YY1	coordinates of the cut
VV1	values of fdefine along the cut
VV2	values of variable along the cut
VVG	gradients of fdefine along the cut
plot	cut, variable along cut
