Description
Each level entry of the sparse_grid_level_sequence
applies to one
expansion within a multi-stage expansion. Current multi-stage
expansions that support sparse grid level sequences include multilevel
polynomial chaos, multifidelity polynomial chaos, or multifidelity
stochastic collocation expansions.
If adaptive refinement is active, then this sequence specifies the starting point for each level within either an individual or integrated refinement approach.
A corresponding scalar specification is documented at, e.g.,
