Normally, it is best to use the FieldClassMapSetFromOptions() command and then set the FieldClassMap type from the options database rather than by using this routine. Using the options database provides the user with maximum flexibility in evaluating the many different solvers. The FieldClassMapSetType() routine is provided for those situations where it is necessary to set the application ordering independently of the command line or options database. This might be the case, for example, when the choice of solver changes during the execution of the program, and the user's application is taking responsibility for choosing the appropriate method. In other words, this routine is not for beginners.
