nonlincut
algorithm
- draws non linear cut through flame front between user defined boundaries
- following the gradient of flame front
- and extracts a 1d profile from the 2d field of variable along the cut
- plots the cut and variable along the cut
syntax
[XMIN,XMAX,YMIN,YMAX,XX1,YY1,VV1,VV2,VVG]=nonlincut(X,Y,XS,YS,fdefine,variable,dl,level,s,iso1,iso2)
example for input
[XMIN,XMAX,YMIN,YMAX,XX1,YY1,VV1,VV2,VVG]=nonlincut(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
