Hi,

I am attempting to do a Geometry Optimization (through Forcite) and I wish to constrain the angle around a center Cu atom to keep it square planar.

Whenever I attempt to refine the structure, these angles become grossly distorted to form a Cu center that I would consider to be non-physical.

If anyone has any experience refining structures while retaining this type of motif, whether in Forcite or another model, that would be an asset to me.

Thanks,

Ben
