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
syntax
intvar=intcutnonlin(X,Y,XS,YS,fdefine,variable,dl,level,s,iso1,iso2)
example for input
intvar=intcutnonlin(X,Y,0.0052,0.0044,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 |
| 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
| Name | description |
|---|---|
| intvar | integral value of variable along the cut |
| plot | cut, variable along cut |
