Output

The Output section decides what your simulation writes down as it runs, and how often. The more you ask it to save, the more disk space the run uses and the slower it runs — so save only what you need to analyze.

Setting	What it controls
Name	A label for the output set you are configuring.
Variable	Which quantity to save (displacement, force, damage, and so on).
Calculation type	How the quantity should be computed or aggregated.
Block id	Which block(s) the output applies to.

Available quantities

Quantity	What you get from it
Displacement	How far each point has moved — the basis for most visualizations.
Force	The forces between points.
Damage	Which bonds have broken — how far the crack has spread.
Partial stress	The stress carried by individual bonds.
Number of neighbors	How many neighbors each point still has connected to it.

Setting	What it controls
Output frequency	How often, in steps, data is written to disk.
Initial output step	The step at which output begins (useful to skip the start).

Tip: displacement and damage are the quantities you will want most often, since they are what the mesh view, plots, and crack analysis use.
