Template Class Observable¶

Defined in File observable.h

Class Documentation¶

template<typename SourceFieldType, typename Operation> class Observable¶

A typed FE expression: a Field, a deal.II view operation, and metadata.

The expression’s value type is the result of invoking its operation on the source Field’s deal.II FEValues view. This keeps FE tensor typing and operation support in deal.II rather than maintaining a parallel algebra in ImmersX.

Public Types

using source_field_type = SourceFieldType ¶

using view_type = typename SourceFieldType::view_type¶

using value_type = std::decay_t<decltype(std::declval<Operation>()(std::declval<const view_type&>(), 0u, 0u))>¶
