Detailed Description

template<unsigned int dim, typename number>
struct SolutionLevel< dim, number >

The solution vectors with respect to on some multigrid level.

solutions is a block vector of all the fields that we keep track of at this level. old_solutions is a vector of with length equal to the number of old states we keep track old. Importantly, for each std::vector entry the block vector has the same shape as solutions.

Remarks

There is a [minor] optimization we could make regarding the old solutions. If a user wants to store up the 2nd old state, we allocate up to the 2nd old state for all fields. This behavior is indiscriminate on whether the user actually needs those vectors, so we could not do that. However, it's painful to deal with and will likely only show minor performance improvements.
