**process area

Description

This post-processing calculates the area of a faset. It can also be used to compute the length of a line boundary set (liset).

Syntax

**process area \(~\,\) *bset bset_name

Example

A practical application is tracking how the cross-sectional area of a specimen changes during necking.

****post_processing
 ***global_post_processing
  **file node
  **deformed
  **process area
   *bset middle_section
****return

Note that **deformed is used to compute the surface of a bset based on the current (deformed) nodal positions. The resulting .post file shows the evolution of the area, for example:

# Time(1)      Area0(2)     Area(3) on bset middle_section
  1.000000e+00 7.853904e-01 5.639460e-01
