Detailed Description

template<class ELEMENT>
class oomph::OneDLagrangianMesh< ELEMENT >

1D mesh parametrised in terms of a 1D Lagrangian coordinate. The Eulerian positions of the nodes are determined by the GeomObject.

template<class ELEMENT >
void oomph::OneDLagrangianMesh< ELEMENT >::assign_default_element_gradients ( )
private

Set the default gradients of the elements.

Set the default (initial) gradients within each element, which are merely the distances between the nodes, scaled by 0.5 because the elements have length 2 in local coordinates. N.B. This only works for QHermiteElements at the moment
