NonlinearProblem
¶ Bases:
object
This is a base class for nonlinear problems which can return the nonlinear function F(u) and its Jacobian J = dF(u)/du.
Constructor
-
F
()¶ Compute F at current point x
-
J
()¶ Compute J = F’ at current point x
-
form
()¶ Function called by Newton solver before requesting F or J. This can be used to compute F and J together
