strnlev3

algorithm

• first calculates (normal and tangential) strain rate values in a 3d field
• then extracts values of strain rate along user defined flamefront
• plots histogram of strain rate values
  
   

syntax

[str3,meanstr3,stdstr3]=strnlev3(X,Y,Z,str,fdefine,level,s)

example for input

[str3,meanstr3,stdstr3]=strnlev3(X,Y,Z,strt,CO2,0.03,'abs')

input arguments

X,Y,Z	vectors defining the rectangular domain
fdefine	variable defining the flame front
level	isolevel defining the flame front
s	switch between absolut and relativ values for level

 

output arguments

str3	values of strain rate along isosurface of flamefront
meanstr3 stdstr3	mean value of strain rate, standard deviation of strain rate
plots	strain rate along flame front surface histogram of strainrate values pdf of strain rate values
