auto walberla::LBWalberlaImpl< FloatType, Architecture >::add_to_storage ( std::string const  tag)
inlineprotected

Convenience function to add a field with a custom allocator.

When vectorization is off, let waLBerla decide which memory allocator to use. When vectorization is on, the aligned memory allocator is required, otherwise cpu_vectorize_info["assume_aligned"] will trigger assertions. That is because for single-precision kernels the waLBerla heuristic in src/field/allocation/FieldAllocator.h will fall back to StdFieldAlloc, yet AllocateAligned is needed for intrinsics to work.
