2D specfem::assembly::mesh_impl::control_nodes

template<>
struct control_nodes<specfem::dimension::type::dim2>

2D control node data structure optimized for computational assembly.

The control nodes define the geometry of each spectral element and are used for coordinate transformations and shape function evaluations.

Public Members

int nspec

Number of spectral elements in the mesh.

int ngnod
