Extract and Linearize

Starting in version 2021, the Stress Linearization tool has been renamed as Extract-Linearize and will support both the Extract Data and Stress Linearization methods.

Extract Data: Extract any contour data at various points along a path defined on solid elements.
Stress Linearization: Extract stress data at various points along a path (also known as stress classification line) defined on solid elements and then calculate linearized stresses based on these extracted values.

Both methods use paths defined on solid elements and therefore, the same path can be used for either method. However, there are some differences in the extraction and calculation part as shown in the table below:

	Extract Data	Stress Linearization
Purpose	Extract any contoured data along a path	Extract stress data along a path and calculate linearized stresses
Resolved in System	Contour Resolved in System	Transformed to a path based local system
Calculation Data Type	Displayed Contour	Base Stress Tensor or Displayed Stress Contour
Plot Options	Distance along path versus Extracted values (single curve)	Distance along path versus Extracted and Linearized values (multiple curves)
