intcutlin
algorithm
- returns the integral value of a variable along a single linear cut across the flame front
- the cut is determined using the tool lincut
- the integral uses the values of variable and
the values of the gradient of fdefine along the cut
and 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 intcutlinb
syntax
intvar=intcutlin(X,Y,XS,YS,NXS,NYS,fdefine,variable,dl,level,s,iso1,iso2)
example for input
intvar=intcutlin(X,Y,0.0052,0.0044,-0.7627,0.6468,Z,temperature,0.00005,0.5,'abs',0.9,0.1)
input arguments
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) |
output arguments
