InitialSeeding

InitialSeeding

is an option for NDSolve and other functions that specifies equations that specify initial seeding values for variables that may be used by iterative algorithms.

Details

  • For differential algebraic equations in NDSolve and other functions, InitialSeeding->{u[t0]==val} indicates that the numerical value val should be used to start finding consistent initial conditions.
  • For stationary nonlinear partial differential equations in NDSolve and other functions, InitialSeeding->{u[x1,]==fun[x1,]} indicates the numerical function fun of the independent variables x1, should be used to get a starting vector on the mesh.
  • Different initial seeding values may lead to different solutions.  »
