flamehot3

algorithm

defines a certain region of a user defined variable var1 to consider,
for example the region were burning takes place
cuts off the values out off that region
for example the region of low heat release
plots the reduced (burning) region
calculates the values of a second user defined variable var2 only in the reduced region of var1

[var1red,var2red]=flamehot3(var1,hval,lval,s,var2)

[heatred,tempred]=flamehot3(heat,1,0.4,'rel',temperature)

var1	matrix of variable defining the burning region
havl lval	highest value of var1 you want to accept values higher than hval are cutt off lowest value of var1 you want to accept values lower than lval are cutt off
var2	matrix of variable you want to consider in the reduced region of var1
s	switch s='abs' for absolut values of hval and lval s='rel' for relative values of hval and lval

var1red	vector containing values of the reduced field of var1
var2red	vector containing values of var2 in the field of var1red
plot	isosurfaces of hval and lval of var1
