Description

Each level entry of the expansion_order_sequence applies to one expansion within a multi-stage expansion. Current multi-stage expansions that support expansion order sequences include multilevel or multifidelity polynomial chaos.

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., expansion_order
