Member Function Documentation

std::string gridripper::amr1d::initcond::BData::getMessage (  )  const [virtual]

Gets the message.

Reimplemented from gridripper::amr1d::InitCond.

GReal_t gridripper::amr1d::initcond::BData::getTime (  )  const [virtual]

Gets the time parameter at the initialization.

The default implementation returns 0.

Returns:
the time

Implements gridripper::amr1d::InitCond.

int gridripper::amr1d::initcond::BData::init ( tvalarray< tvector< Grid * > > &  grids,
PDE *  pde,
GReal_t  dt,
int  r,
int  maxlevel,
int  bufzone,
AMError *  amerr,
GReal_t  maxerr 
) throw (InitCond::Exception&)

Creates and initializes base grid and initial subgrids.

Parameters:
grids array of all grids
pde the PDE
dt the time step
r refinement ratio
maxlevel maximum refinement level
bufzone buffer zone size
amerr error function
maxerr error tolerance
Returns:
the finest refinement level
bool gridripper::amr1d::initcond::BData::isAppended ( const std::string &  fname  )  const [virtual]

Should the output be appended to an existing data file?

Returns:
true if output should be appended, false if an existing data file can be overwritten

Reimplemented from gridripper::amr1d::InitCond.

bool gridripper::amr1d::initcond::BData::isOnInitialHypersurface (  )  const [virtual]

Is the the initial condition applied on the initial hypersurface?

Returns:
true if it is applied on the initial hypersurface, false otherwise

Reimplemented from gridripper::amr1d::InitCond.
