Attempting to perform relaxation using initial lattice constant guess of 2.5 Angstroms


Failed to perform relaxation using initial lattice constant guess of 2.5 Angstroms
Exception message:
Attempted to evaluate energy at lattice spacing ([2.5]) below the minimum allowed value (2.7540000004425673).  This may mean that the model does not possess close-range repulsive forces to prevent system collapse.
