curv3new

algorithm

  • calculates curvature values in a 3d field:
    mean curvature, gauss curvature and principal curvatures
  • calculates curvature of a surface given in implicit form (Article of Hughes)
  • note: curv3new calculates values of a matrix;
  • use extract3 after calculation, to extract curvature values along isosurface of flame front

syntax

[KG,H,K1,K2]=curv3new(X,Y,Z,fdefine)

example for input

[KH,H,K1,K2]=curv3new(X,Y,Z,CO2)

input arguments

X,Y,Z

vectors defining the rectangular domain

fdefine

variable defining the flame front

output arguments

KG

Gauss curvature (matrix)

H

mean curvature (matrix)

K1, K2

principal curvatures (matrix)

matlab tools required

  • gradient
