Function Documentation

localIDtoGlobal()

constexpr uint64_t WarpXUtilIO::localIDtoGlobal	(	int const	id,
		int const	cpu
	)

A helper function to derive a globally unique particle ID

Parameters

[in]	id	AMReX particle ID (on local cpu/rank), AoS .id
[in]	cpu	AMReX particle CPU (rank) at creation of the particle, AoS .cpu

Returns

global particle ID that is unique and permanent in the whole simulation

bool WarpXUtilIO::WriteBinaryDataOnFile	(	std::string	filename,
		const amrex::Vector< char > &	data
	)

A helper function to write binary data on disk.

Parameters

[in]	filename	where to write
[in]	data	Vector containing binary data to write on disk return true if it succeeds, false otherwise
