NonlinearVariationalProblem
¶ This class represents a nonlinear variational problem:
Find u in V such that
F(u; v) = 0 for all v in V^,where V is the trial space and V^ is the test space.
Create nonlinear variational problem, shared pointer version. The Jacobian form is specified which allows the use of a nonlinear solver that relies on the Jacobian (using Newton’s method).
