FEComputeData(const EquationSystems &es, const Point &pin)
Constructor.
void disable_derivative()
Disable the computation of shape gradients (dshape).
This is the EquationSystems class.
const EquationSystems & equation_systems
Const reference to the EquationSystems object that contains simulation-specific data.
class FEComputeData hides arbitrary data to be passed to and from children of FEBase through the FEIn...
const Point & p
Holds the point where the data are to be computed.
Real phase
Storage for the computed phase lag.
std::vector< Gradient > dshape
Storage for the computed shape derivative values.
std::vector< std::vector< Real > > local_transform
Storage for local to global mapping at p.
The libMesh namespace provides an interface to certain functionality in the library.
Real speed
The wave speed.
void clear()
Clears the output data completely.
void init()
Inits the output data to default values, provided the fields are correctly resized.
Number frequency
The frequency to evaluate shape functions including the wave number depending terms.
std::vector< Number > shape
Storage for the computed shape function values.
bool _need_dshape
variable indicating whether the shape-derivative should be computed or not.
DIE A HORRIBLE DEATH HERE typedef LIBMESH_DEFAULT_SCALAR_TYPE Real
void enable_derivative()
Enable the computation of shape gradients (dshape).
A Point defines a location in LIBMESH_DIM dimensional Real space.
