"Nettet22. mai 2024 · Internal coordinates have numerical instabilities when some of the angles approach 180 degrees. If these angles are already linear from the very start of the optimization, the program can construct the internal coordinates in such a way that they do not include the linear angles, or at least not in a way that causes numerical instabilities.

NettetThis error typically occurs when optimization starts at a highly symmetric structure, which looses some of its symmetry properties on optimization due to an incorrect definition of Z-matrix variables. In the rare case that the symmetry of the system should not be used, one can actually force the program to ignore symmetry completely using the
