Basically it is part of an ab-plane of the crystal. I want to optimize part of this structure in the ab-plane which coincides with the xy-plane of my input coordinates and I do not want it to be able to move in the z-direction. Is there anyway to freeze the z-component using cartesian coordinates or is there anyway to achieve this constrained optimization in a plane?

Keep updated with what's new in the modeling world, read executive summaries of the latest literature and stay in touch with pears. please check it out and tell me what you think... If any of you is interested in writing for the blog I'd be very happy if you contact me. Cheers, Nir London.

What means the colors? Red = negative density? Blue = positive density? excuse for the question and for my english Thanks in advance to all, Regards, Carlos Javier
