Struct Documentation

struct ripple::FOExtrapLoader : public ripple::PaddingLoader<FOExtrapLoader>

The FOExtrapLoader is an implementation of an BoundaryLoader which copies the data from the closest valid cell inside the domain to all padding cells.

It performs a first order extrapolation of the data in an iterator into the padding data for the iterator.

Public Functions

template<typename Iterator, typename Dim>
constexpr auto load_front(Iterator &&it, int index, Dim &&dim) const noexcept -> void

Loads the front padding in the dim dimension, using the value of the index in the dimension to find the appropriate cell.

Parameters

• it: An iterator to the padding cell to load.

• index: The index of the padding cell in the dimension.

• dim: The dimension to load the padding in.

Template Parameters

• Iterator: The type of the iterator.

• Dim: The type of the dimension specifier.

template<typename Iterator, typename Dim>
constexpr auto load_back(Iterator &&it, int index, Dim &&dim) const noexcept -> void

Loads the back padding in the dim dimension, using the value of the index in the dimension to find the appropriate cell.

Parameters

• it: An iterator to the padding cell to load.

• index: The index of the padding cell in the dimension.

• dim: The dimension to load the padding in.

Template Parameters

• Iterator: The type of the iterator.

• Dim: The type of the dimension specifier.
