Metrics for Edge Elements

The metrics used for edge elements in Trelis are summarized in the following table:

Function Name
Dimension
Full Range
Acceptable Range
Length
L^0
0 to inf
None

Quality Metric Definitions:

Length: Distance between beginning and ending nodes of an edge

Comments on Algebraic Quality Measures

  1. The quality command for edge length only accepts edge elements as input; it does not accept geometry as input.
  2. The length metric is currently only available for edge elements. Edge elements are created by default when curves and surfaces are meshed. Edge elements are not created for interior volume elements.
