64: SNESRegisterDynamic - Adds a method to the nonlinear solver package.
66: Synopsis:
67: PetscErrorCode SNESRegisterDynamic(char *name_solver,char *path,char *name_create,PetscErrorCode (*routine_create)(SNES))
69: Not collective
71: Input Parameters:
72: + name_solver - name of a new user-defined solver
73: . path - path (either absolute or relative) the library containing this solver
74: . name_create - name of routine to create method context
75: - routine_create - routine to create method context
77: Notes:
78: SNESRegisterDynamic() may be called multiple times to add several user-defined solvers.
80: If dynamic libraries are used, then the fourth input argument (routine_create)
81: is ignored.
83: Environmental variables such as ${PETSC_ARCH}, ${PETSC_DIR}, ${PETSC_LIB_DIR},
84: and others of the form ${any_environmental_variable} occuring in pathname will be
85: replaced with appropriate values.
87: Sample usage:
88: .vb
89: SNESRegisterDynamic("my_solver",/home/username/my_lib/lib/libg/solaris/mylib.a,
90: "MySolverCreate",MySolverCreate);
91: .ve
93: Then, your solver can be chosen with the procedural interface via
94: $ SNESSetType(snes,"my_solver")
