The SPlane interface is used to create section planes that can be used to perform section cuts of the model for further analysis. Various methods of cutting model cross sections are available, and the model can be animated in section cut mode.
The cross section plane can be fixed to space, fixed to the model and a lagrangian type section cutting is also available. If the model is fringed with plastic strains prior to cutting section, then the section cut will be fringed also. Model can be clipped on either side of the section plane by Off/Clip-/Clip+.

This sub-panel allows changing color and with of section cut lines, projecting the section cut to true view and turning part thickness and vector plotting of element quantities at section level. Section cuts can be exported in various formats.

Allows plotting crush of a point in the model with respect to a plane. This plane can be fixed to space or moving with the model.

Various measurements methods are available on section cuts: coordinate, distance, 3pt-angle, 3pt-radius and 2ln-angle. Although the main application for this is for metal forming simulations, it has wide range of applications in other fields.

Section cut line plotting allows for plotting section properties (like shell thickness) on xy-plots. x-axis on the xy-plot is the length of the section cut line developed to a straight line. The main application of this is in metal forming simulations.

LS-DYNA has a facility to calculate and output section forces by user defining *DATABASE_CROSS_SECTION. This interface allows sections to be defined interactively and LS-PrePost computes the section quantities if shell resultants are available in d3plot files. Generally this data is available in d3plot files unless it is turned off by the use of *DATABASE_EXTENT_BINARY options.

Section plane definitions can be saved and loaded. This allows users define sections once and save them for future model revision use. Often users want to cut a cross section on various model iterations at the same specific location.
