# quadrature_order_sequence

Sequence of quadrature orders used in a multi-stage expansion

Specification

- Alias: None

- Arguments: INTEGERLIST

Child Keywords:

Required/Optional | Description of Group | Dakota Keyword | Dakota Keyword Description
--- | --- | --- | ---
Optional | dimension_preference | A set of weights specifying the realtive importance of each uncertain variable (dimension)
Optional (Choose One) | Quadrature Rule Nesting | nested | Enforce use of nested quadrature rules if available
non_nested | Enforce use of non-nested quadrature rules

Description

Each level entry of the `quadrature_order_sequence` applies to one expansion within a multi-stage expansion. Current multi-stage expansions that support quadrature order 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., `quadrature_order`
