123/*@C
124 CharacteristicSetType - Builds Characteristic for a particular solver.
125
126 Logically Collective on Characteristic
127
128 Input Parameters:
129+ c - the method of characteristics context
130- type - a known method
131
132 Options Database Key:
133. -characteristic_type <method> - Sets the method; use -help for a list
134 of available methods
135
136 Notes:
137 See "include/petsccharacteristic.h" for available methods
138
139 Normally, it is best to use the CharacteristicSetFromOptions() command and
140 then set the Characteristic type from the options database rather than by using
141 this routine. Using the options database provides the user with
142 maximum flexibility in evaluating the many different Krylov methods.
143 The CharacteristicSetType() routine is provided for those situations where it
144 is necessary to set the iterative solver independently of the command
145 line or options database. This might be the case, for example, when
146 the choice of iterative solver changes during the execution of the
147 program, and the user's application is taking responsibility for
148 choosing the appropriate method. In other words, this routine is
149 not for beginners.

219 CharacteristicRegister - Adds a solver to the method of characteristics package.
220
221 Not Collective
222
223 Input Parameters:
224+ name_solver - name of a new user-defined solver
225- routine_create - routine to create method context
226
227 Sample usage:
228.vb
229 CharacteristicRegister("my_char", MyCharCreate);
230.ve
231
232 Then, your Characteristic type can be chosen with the procedural interface via
233.vb
234 CharacteristicCreate(MPI_Comm, Characteristic* &char);
235 CharacteristicSetType(char,"my_char");
236.ve
237 or at runtime via the option
238.vb
239 -characteristic_type my_char
240.ve
241
242 Notes:
243 CharacteristicRegister() may be called multiple times to add several user-defined solvers.
