README

------------------------------------------------------------------------------
Data structure:
------------------------------------------------------------------------------

elem: Three vertices forming a triangle. Given in counter-clockwise order

edge: two vertices forming an edge. For a boundary edge, when we go from
vertex one to vertex two, the computational domain lies to the left of the
edge

tedge: Triangles adjacent to an edge; left is first and then right.

esue: Elements surrounding an element. Required only for implicit scheme

vedge: The vertices opposite to an edge; left first then right. Used for
reconstruction.

spts: Solid wall points

bdedge: For each solid wall point, the two boundary edges sharing that point.
Used for calculating wall normal, which is required for inviscid bc.

esubp: Elements surrounding a boundary point. Required for vertex averaging.

ptype: Type of vertex.

Changelog
------------------------------------------------------------------------------
Following functions have been changed
   solid_flux
   farfield_flux
   clcd
   costfunc

Linear interpolation has been replaced with first order treatment. This would
be more robust while results dont seem to be affected.

* Added entropy fix for |u| eigenvalues in roe flux
