  In the light of recent experimental developments, increasing attention is
devoted to nuclear phenomena related to rotational excitations of exotic
intrinsic nuclear configurations that often lack symmetries present in the
majority of nuclei. Examples include configurations with a non-vanishing
octupole moment. In order to describe this kind of states, we have developed a
new computer code to solve the self-consistent mean-field equations, able to
use most of today's effective Skyrme interactions and working in
coordinate-space. We report on the development of MOCCa, a code based on the
same principles as EV8, but offering the user individual control on many
symmetry assumptions. In addition, the HF+BCS pairing treatment of EV8 has been
generalised to the full machinery of Hartree-Fock-Bogoliubov transformations.
We discuss as example the static fission barrier of $^{226}$Ra, prefacing
extended studies in the region, using the recent series of Skyrme
parameterizations SLy5s1 through SLy5s8.
