normtoff
algorithm
- calculates and extracts normal components along flame front
using the tools normal and extract - calculates starting points and directions for linear cuts along flame front
- plots normals along flame front
note: by definition normals point to fresh gas for premixed flames or to the oxidizer side for non- premixed flames
syntax
[SNORM]=normtoff(X,Y,fdefine,level,s)
example for input
[SNORM]=normtoff(X,Y,Z,0.5,'abs')
input arguments
| Name | description |
|---|---|
| X,Y | vectors defining the rectangular domain |
| fdefine | variable defining the flame front |
| level | isovalue of variable |
| s | switch,'rel' if level is relativ; 'abs' if level is absolut |
output arguments
| Name | description |
|---|---|
| [SNORM] | four line matrix containing: xs,ys: starting points of normal vectors, nxs, nys: components of normal vectors |
| plot | flamefront, normals |
