nonlinextract

algorithm

  • draws a non linear cut through the flame front through the whole domain
  • following the gradient of the variable defining the flame front
  • and extracts a 1d profile from the 2d field of a user defined variable along the cut
  • nonlinextract is intended to prepare nonlincut in order to consider
    only a user defined part of the cut (for example the part inside the flame front)
  • nonlinextract does not plot the cut, the figure below is only for explanation,the plot will be done in nonlincut
    nonlincutfull 

syntax

[XX,YY,VV]=nonlinextract(XMIN,XMAX,YMIN,YMAX,NX,NY,variable,XS,YS,fdefine,DL,X,Y) 

 

example for input

[XX,YY,VV]=nonlinextract(0.0,0.01,0.0,0.01,401,401,temperature,0.0052,0.0044,fdefine,0.0001,X,Y) 

 

input arguments

Name description
X,Y vectors defining the rectangular domain
XMIN,XMAX,YMIN,YMAX boundaries of domain
variable variable to be extracted along the cut
XS,YS coordinates of starting point of the cut
fdefine variable defining flamefront and gradient for the direction of the cut

output arguments

Name description
XX,YY coordinates of the cut
VV values of variable along the cut
