Under Quality, select a plot Resolution: Finer, Fine, Normal, Coarse, No refinement, or Custom. A higher resolution means that elements are split into smaller patches during rendering. The Finer, Fine, Normal, Coarse use heuristics to determine a suitable resolution. For Custom, enter a positive integer (default: 1) in the Element refinement field. A higher value means higher resolution. The refinements is done by subdividing the element edges. See the following figure, which shows the refinement levels 1, 2, and 3:

Custom refinement applies to the base dataset. The number of elements in the model can therefore increase radically if the plot uses, for example, a revolve dataset, since the refinement is applied to the solution dataset.

None: to plot elements independently.

Inside material domains (the default): to smooth the quantity within domains shared by the same material but not across material boundaries. Here, material is interpreted in a wider sense than just a physical material. Some physics interfaces implement material groups, which are sets of domains that are considered as being suitable for internal smoothing.
|
-
|
Internal: to smooth the quantity inside the geometry, but no smoothing takes place across borders between domains with different settings.
|
-
|
Everywhere: to apply smoothing to the entire geometry.
|
-
|
Expression: to use an expression to indicate where smoothing should occur. Enter an expression in the Expression field such that smoothing occurs where the expression is continuous. The default expression is dom, the domain variable, which is equivalent to the Internal smoothing. You can also — in a surface plot, for example — use material.domain, which is an indicator variable for domains that share the same material (see Material Group Indicator Variables) and is equivalent to the Inside material domains setting.

Under Quality, the Recover default is Off because the accurate derivative recovery takes processing time. This recovery is a polynomial-preserving recovery that recovers fields with derivatives such as stresses or fluxes with a higher theoretical convergence than smoothing (see Polynomial-Preserving Derivative Recovery).

-
|
Within domains: to perform recovery inside domains.
|
-
|
Everywhere: to apply recovery to all domain boundaries.
|
The Recover option only affects variables that are defined on domains.
