I noticed that when trying geometry optimizations on periodic systems in DMol, using Materials Studio 7.0, one is not allowed to use the B3LYP hybrid functional.  This is one of the most useful and accurate functionals available, for geometries and electronic structure, so it is a big bummer to not be able to use it for periodic systems in DMol.  Are there any plans to implement that in the near future?  How about suggestions for alternatives?
