  In this manuscript we provide an outline of the numerical methods used in
implementing the density constrained time-dependent Hartree-Fock (DC-TDHF)
method and provide a few examples of its application to nuclear fusion. In this
approach, dynamic microscopic calculations are carried out on a
three-dimensional lattice and there are no adjustable parameters, the only
input is the Skyrme effective NN interaction. After a review of the DC-TDHF
theory and the numerical methods, we present results for heavy-ion potentials
$V(R)$, coordinate-dependent mass parameters $M(R)$, and precompound excitation
energies $E^{*}(R)$ for a variety of heavy-ion reactions. Using fusion barrier
penetrabilities, we calculate total fusion cross sections
$\sigma(E_\mathrm{c.m.})$ for reactions between both stable and neutron-rich
nuclei. We also determine capture cross sections for hot fusion reactions
leading to the formation of superheavy elements.
