Parameters
----------
filename : str
The output file name.
ebcs : Conditions instance, optional
The essential (Dirichlet) boundary conditions. If not given,
`self.conf.ebcs` are used.
epbcs : Conditions instance, optional
The periodic boundary conditions. If not given, `self.conf.epbcs`

force : bool
If True, sequential nonzero values are forced to individual `ebcs`
so that the conditions are visible even when zero.
default : float
The default constant value of state vector.
