Curves
Curve entities define and store xy data and are associated with a plot entity.
Curves do not have a display state. However, the display of a curve in a xy plot window is controlled by the display state and active state of its associated plot.
Abaqus Cards
| Card | Description |
|---|---|
| *AMPLITUDE | Define an amplitude curve Note: For Standard and Explicit profiles:
The TABULAR definition reads either pairwise entries (new) or four pairs of values per dataline (old). The EQUALLY SPACED option has been updated to the new format as well. The old format is required by users using pre 6.9 Abaqus solver. The reader can read both formats. The card will be exported the same way as it was imported. The card image allows you to switch between both formats. |
EXODUS Cards
| Card | Description |
|---|---|
| Function | Time, frequency and/or spatially dependent functions for transient and frequency response analysis. |
LS-DYNA Cards
The output of curves creates a *DEFINE_CURVE or Structured Card 22 using Option 0.
*DEFINE_CURVE can be changed to *DEFINE_TABLE in the card previewer. When DEFINE_CURVE is changed to DEFINE_TABLE, the number of curves the table should contain depends on the XY curves that are referenced by a load, material, component, property, and so on are output.
Upon input, the *DEFINE_CURVE and *DEFINE_TABLE/Card 22 cards are read and placed in a plot called LS-DYNA Load Curves. Upon input, references to curves are preserved and are output along with the card, such as material, component, property and load.
| Card | Description |
|---|---|
| *DEFINE_CURVE | Define a curve. |
| *DEFINE_CURVE_SMOOTH | Define a smoothly varying curve using few parameters. |
| *DEFINE_CURVE_TRIM | Define a curve for trimming. |
| *DEFINE_CURVE_TRIM_3D | Define a curve for trimming. Trimming is processed based on the element normal rather than the vector. |
| *DEFINE_FUNCTION | Define a function that can be referenced by a limited number of keyword options. |
| *DEFINE_TABLE | Define a table. |
| *DEFINE_TABLE_2D | Define a table. |
| *DEFINE_TABLE_3D | Define a table. |
