Detailed Description

template<typename ScalarT>
class terra::linalg::VectorQ1Scalar< ScalarT >

Q1 scalar finite element vector on a distributed shell grid.

Same layout as required for tensor-product wedge elements.

Satisfies the VectorLike concept (see vector.hpp). Provides masked grid data and operations for scalar fields.
