Member Function Documentation

addInitOption()

void bitpit::PetscManager::addInitOption

(

const std::string &

option

)

Add an initialization option.

Parameters

option

is the option that will be added

Definition at line 482 of file system_solvers_large.cpp.

addInitOptions() [1/2]

void bitpit::PetscManager::addInitOptions

(

const std::vector< std::string > &

options

)

Add initialization options.

Parameters

options

are the options that will be added

Definition at line 521 of file system_solvers_large.cpp.

addInitOptions() [2/2]

void bitpit::PetscManager::addInitOptions	(	int	argc,
		char **	argv )

Add initialization options.

Parameters

argc

is a non-negative value representing the number of arguments passed to the program from the environment in which the program is run

argv

is a pointer to the first element of an array of argc + 1 pointers, of which the last one is null and the previous ones, if any, point to null-terminated multibyte strings that represent the arguments passed to the program from the execution environment. If argv[0] is not a null pointer (or, equivalently, if argc > 0), it points to a string that represents the name used to invoke the program, or to an empty string. The value of argv[0] is not propagated to the system solver, the solver will see a dummy name.

Definition at line 505 of file system_solvers_large.cpp.

areOptionsEditable()

bool bitpit::PetscManager::areOptionsEditable

(

)

const

Check if initialization options are editable.

Returns

Returns true if initialization options are editable, false otherwise.

Definition at line 582 of file system_solvers_large.cpp.

clearInitOptions()

void bitpit::PetscManager::clearInitOptions

(

)

Clear initialization options

Definition at line 535 of file system_solvers_large.cpp.

finalize()

bool bitpit::PetscManager::finalize

(

)

PETSc finalization.

If PETSc finalization was already called, it will not be called again.

If MPI initialization has been performed by the PETSc manager and a permanent finalization is requested, this function will call MPI finalization.

Returns

Return true is PETSc has been finalized by this function, false if PETSc was already finalized.

Definition at line 693 of file system_solvers_large.cpp.

initialize()

bool bitpit::PetscManager::initialize

(

bool

debug

)

PETSc initialization.

If PETSc is already initialized, this function is a no-op.

If the MPI initialization has not be called yet, it will be called by this function.

The function can be called more than once.

Parameters

debug

if set to true, turns on logging of objects and events, once the logging is enabled it cannot be disabled

Returns

Return true is PETSc has been initialized by this function, false if PETSc was already initialized.
