Detailed Description

template<unsigned int dim, unsigned int spacedim>
class FEValuesData< dim, spacedim >

Class FEValuesData holds the arrays of data computed by Mapping and FiniteElement.

Definition at line 46 of file fe_values.hh.

Member Function Documentation

template<unsigned int dim, unsigned int spacedim>
void FEValuesData< dim, spacedim >::allocate ( unsigned int  size,
UpdateFlags  flags,
bool  is_scalar = true 
)

Resize the data arrays.

Parameters
sizeNumber of quadrature points.
