fedoo.ListBC

class ListBC(l=None, name='')

List of boundary conditions.

Class that define a list of ordered elementary boundary conditions (the bc are applied in the list order). Derived from the python list object.

Notes

Several boundary conditions may share some dof:

• The generalized forces of the Neumann bc are summed.

• For Dirichlet bc, the last one in the list is applied. This is reported if the prescribed values are different (see check()).

The attribute check_mode defines what is done when incompatible boundary conditions are found the first time the list is applied to a problem: "warn" (default) emits a BoundaryConditionWarning, "raise" raises a BoundaryConditionConflict error and "ignore" disables the check.

Methods

ListBC.__getitem__(items)
ListBC.__len__()
ListBC.add(*args, **kargs)	Add a boundary condition to the ListBC object, and then to the associated problem if there is one.
ListBC.append(bc)
ListBC.check([problem, t_fact])	Look for boundary conditions applied twice on the same dof.
ListBC.extend(iterable)
ListBC.generate(problem[, t_fact, t_fact_old])
ListBC.get_all()
ListBC.initialize(problem)
ListBC.list_all()
ListBC.mpc(*args, **kargs)	Add a linear multi-point constraint to the list of boundary conditions.
ListBC.register_global_dofs(problem)	Register global DOFs required by this boundary condition.
ListBC.remove(bc)
ListBC.str_condensed()	Return a condensed one line str describing the object

ListBC.check_mode	"warn", "raise" or "ignore".
