/* ERROR/WARNING messages:
E: Atom_style tri can only be used in 3d simulations
Self-explanatory.
E: Per-processor system is too big
The number of owned atoms plus ghost atoms on a single
processor must fit in 32-bit integer.
E: Invalid atom ID in Atoms section of data file
Atom IDs must be positive integers.
E: Invalid atom type in Atoms section of data file
Atom types must range from 1 to specified # of types.
E: Invalid density in Atoms section of data file
Density value cannot be <= 0.0.
E: Assigning tri parameters to non-tri atom
Self-explanatory.
E: Invalid shape in Triangles section of data file
Two or more of the triangle corners are duplicate points.
E: Inconsistent triangle in data file
The centroid of the triangle as defined by the corner points is not
the atom coordinate.
E: Insufficient Jacobi rotations for triangle
The calculation of the intertia tensor of the triangle failed. This
should not happen if it is a reasonably shaped triangle.
