cell_chemistry_kernels::AdvanceFunctor Struct Reference

Advances the cells of a queue over dt, writes their partial densities, last sub-step and cost, and counts failures. The temperature seed stays as the RHS left it: halo copies of a cell get no chemistry, and their seeds must follow the owner's. More...

Detailed Description

Advances the cells of a queue over dt, writes their partial densities, last sub-step and cost, and counts failures. The temperature seed stays as the RHS left it: halo copies of a cell get no chemistry, and their seeds must follow the owner's.
