8 : : \brief Mix number-fraction beta SDE coefficients policies
9 : : \details This file defines coefficients policy classes for the mix
10 : : number-fraction beta SDE, defined in DiffEq/MixNumberFractionBeta.h.
11 : :
12 : : General requirements on mix number-fraction beta SDE coefficients policy
13 : : classes:
14 : :
15 : : - Must define a _constructor_, which is used to initialize the SDE
16 : : coefficients, b, S, kappa, rho2, and rcomma. Required signature:
17 : : \code{.cpp}
18 : : CoeffPolicyName(
19 : : tk::ctr::ncomp_t ncomp,
20 : : const std::vector< kw::sde_bprime::info::expect::type >& bprime_,
21 : : const std::vector< kw::sde_S::info::expect::type >& S_,
22 : : const std::vector< kw::sde_kappaprime::info::expect::type >& kprime_,
23 : : const std::vector< kw::sde_rho2::info::expect::type >& rho2_,
24 : : const std::vector< kw::sde_rcomma::info::expect::type >& rcomma_,
25 : : std::vector< kw::sde_bprime::info::expect::type >& bprime,
26 : : std::vector< kw::sde_S::info::expect::type >& S,
27 : : std::vector< kw::sde_kappaprime::info::expect::type >& kprime,
28 : : std::vector< kw::sde_rho2::info::expect::type >& rho2_,
29 : : std::vector< kw::sde_rcomma::info::expect::type >& rcomma_ );
30 : : \endcode
31 : : where
32 : : - ncomp denotes the number of scalar components of the system of
33 : : mix number-fraction beta SDEs.
34 : : - Constant references to bprime_, S_, kprime_, rho2_, and rcomma_, which
35 : : denote five vectors of real values used to initialize the parameter
36 : : vectors of the system of mix number-fraction beta SDEs. The length of
37 : : the vectors must be equal to the number of components given by ncomp.
38 : : - References to bprime, S, kprime, rho2_, and rcomma, which denote the
39 : : parameter vectors to be initialized based on bprime_, S_, kprime_,
40 : : rho2_, and rcomma_.
41 : :
42 : : - Must define the static function _type()_, returning the enum value of the
43 : : policy option. Example:
44 : : \code{.cpp}
45 : : static ctr::CoeffPolicyType type() noexcept {
46 : : return ctr::CoeffPolicyType::DECAY;
47 : : }
48 : : \endcode
49 : : which returns the enum value of the option from the underlying option
50 : : class, collecting all possible options for coefficients policies.
51 : :
52 : : - Must define the function _update()_, called from
53 : : MixNumberFractionBeta::advance(), updating the model coefficients.
54 : : Required signature:
55 : : \code{.cpp}
56 : : void update(
57 : : char depvar,
58 : : ncomp_t ncomp,
59 : : const std::map< tk::ctr::Product, tk::real >& moments,
60 : : const std::vector< kw::sde_bprime::info::expect::type >& bprime,
61 : : const std::vector< kw::sde_kappaprime::info::expect::type >& kprime,
62 : : std::vector< kw::sde_b::info::expect::type >& b,
63 : : std::vector< kw::sde_kappa::info::expect::type >& k ) const {}
64 : : \endcode
65 : : where _depvar_ is the dependent variable associated with the mix
66 : : number-fraction beta SDE, specified in the control file by the user, _ncomp_ is
67 : : the number of components in the system, _moments_ is the map associating
68 : : moment IDs (tk::ctr::vector< tk::ctr::Term >) to values of statistical
69 : : moments, _bprime_, _kprime_ are user-defined parameters, and _b_, _k_ are
70 : : the SDE parameters computed, see DiffEq/MixNumberFractionBeta.h.
