intcutnonlin

algorithm

returns the integral value of a variable along a single non linear cut across the flame front
the cut is determined using the tool nonlincut
the integral uses the values of variable and the values of the gradient of fdefine along the cutand the matlab tool trapz for the integration
plots the cut and variable along the cut
for batch modus along curvilinear coordinate of flame front use intcutnonlinb

intvar=intcutnonlin(X,Y,XS,YS,fdefine,variable,dl,level,s,iso1,iso2)

intvar=intcutnonlin(X,Y,0.0052,0.0044,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
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
intvar	integral value of variable along the cut
plot	cut, variable along cut
