General Convergence Issues with NWChem

Thanks, this helps with my convergence criteria issues, but I am still having problems with many calculations having a "dimension mismatch error". In these cases it seems that the calculation doesn't not even begin to do driver iterations. On these calculations it does "Step 0", then begins printing out the stretch, bend and torsion data, then crashes:

Units are Angstrom for bonds and degrees for angles
