template<class MParrs >

AMREX_GPU_DEVICE void spades::models::Phold::InitMessageOp::operator() ( const MParrs & msg_parrs, const int n, amrex::RandomEngine const & engine ) const

inline

Callable operator to initialize an message.

Template Parameters

MParrs

type of the message particle array

Parameters

msg_parrs	message particle array
n	index of the particle
engine	random engine

        {
            const amrex::Real ts =
                random_exponential(m_lambda, engine) + m_lookahead;

m_lambda

amrex::Real spades::models::Phold::InitMessageOp::m_lambda {1.0}

Width of exponential distribution (optional user input) smaller values of lambda = larger variance in random values larger values of lambda = smaller variance in random values

{1.0};

m_lookahead

amrex::Real spades::models::Phold::InitMessageOp::m_lookahead {1.0}

Lookahead value (optional user input)

{1.0};

m_messages_per_lp

int spades::models::Phold::InitMessageOp::m_messages_per_lp {1}

Initial messages per LP.

{1};
