Detailed Description

Class used for caching additional information for elements such as the volume and centroid.

This also supports the ghost elements used in the finite volume setting (for the time being).

Member Data Documentation

_centroid

Point ElemInfo::_centroid

protected

Centroid of the element.

Definition at line 51 of file ElemInfo.h.

Referenced by centroid().

_coord_transform_factor

Real ElemInfo::_coord_transform_factor

protected

Cached coordinate transformation factor.

Definition at line 53 of file ElemInfo.h.

Referenced by coordFactor(), and coordFactor().

_dof_indices

std::vector<std::vector<dof_id_type> > ElemInfo::_dof_indices

protected

Cached dof indices mainly for segregated linear FV evaluations with the following structure: _dof_indices[system_number][variable_number] = dof_index Systems with no FV variables will store an empty vector and should not be accessed.

This will be checked through multiple asserts in the assembly routines. Furthermore, if the current variable is not active on the subdomain or if it is an FE variable of this element, we return an invalid_dof_index.

_elem

const Elem* const ElemInfo::_elem

protected

Reference to the element in libmesh.

_volume
