Detailed Description

template<int D, class T>
class Pscf::Rp::BdStep< D, T >

Template for abstract base class for Brownian dynamics (BD) steps.

The virtual step() method must generate a single BD step. The step generally includes a random change in field components other than the pressure-like field, followed by use of a Compressor to adjust the pressure-like field to re-establish a homogeneous total monomer concentration.

Specializations of this class template are used as base classes for two closely analogous class templates, both also named BdStep, that are defined in Rpc and Rpg namespaces for use in the pscf_rpc and pscf_rpg programs, respectively.

Template parameters:

D : dimension of space (D=1, 2, or 3)
T : Types class (Rpc::Types<D> or Rpg::Types<D>)

Template parameters:

D dimension of space (1, 2, or 3)
T Types class (Rpc::Types<D> or Rpg::Types<D>)
