D3PLOT 22.1

*DEFINE_HEX_SPOTWELD_ASSEMBLY

These are drawn and contoured using the solid elements that define the spotweld assembly. All of the solid elements are contoured using the same colour as the LSDA file contains a single value for each assembly. They are labeled as HAn .

Spheres

In some plots where the spotwelds lay between panels and can not be seen using the version 94 symbols swapping to spheres which protrude through the panels can allow the spotwelds to be seen.

Sphere Size

To make it easier to view the spotweld locations the size of the spheres can be controlled using a number of different options.

Panel Gap x < factor >

D3PLOT will calculate a panel gap based on the initial geometry of each weld.

CONSTRAINED_SPOTWELD	0.5 x the distance between the 2 nodes
CONSTRAINED_GENERALIZED_WELD_	0.5 x the distance between the 2 nodes
MAT_SPOTWELD (beams)	0.5 x the distance between the 2 nodes
MAT_SPOTWELD (solids)	0.5 x the average of the distance between the 4 pairs of of nodes that make up the edges of the spotweld.
DEFINE_HEX_SPOTWELD_ASSEMBLY	0.5 x the average of the distance between all of the pairs of nodes that make up the edges of the solids.

True Radius x < factor >

This uses the radius of each spotweld. For each spotweld type D3PLOT will use the following for each radius.

CONSTRAINED_SPOTWELD	0.5 x the distance between the 2 nodes
CONSTRAINED_GENERALIZED_WELD_	0.5 x the distance between the 2 nodes
MAT_SPOTWELD (beams)	0.5 x beam cross section diameter
MAT_SPOTWELD (solids)	If the weld was created as a PRIMER connection then 0.5 x the connection diameter will be used. If no connection data is available then D3PLOT will calculate a radius based on the solid geometry.
DEFINE_HEX_SPOTWELD_ASSEMBLY	D3PLOT will calculate a radius based on the solid elements geometry.

Fixed radius < value >

This uses the stipulated fixed radius size. This can sometimes be useful if some of the spotwelds are very small and can not easily be seen.

Scale symbols by value

If a Fixed radius is used then the fixed radius can be scaled according to the magnitude of the data value when spotweld data components are contoured.

Minimum size (%)

If a Fixed radius is used then this option can be used to set a lower limit when the size is scaled by value.

Version 94 symbols size

This option can be used to scale the size of the version 9.4 symbols.

Show Failure Time

This option will automatically annotate any spotwelds that fail during the analysis with the failure time. Only spotwelds with a failure time greater than 0.0 are displayed.

The failure times displayed are taken from the last state in the LSDA (binout) file and are constant regardless of the plot state time.

Don't display unfailed spotwelds

To make it easier to identify the spotwelds that fail this option can be used to automatically turn off the display of any spotwelds that do not fail during the analysis

As with the display of the failure time the information from the last state in the LSDA (binout) file is used to determine which spotwelds fail.

Spotweld Preference Options

The following preference options can be used to set the default options used to display spotwelds

d3plot*swld_symbol	Symbol for type for Spotwelds, either DEFAULT or SPHERE
d3plot*swld_quality	Quality of Spotweld sphere symbol (1-5)
d3plot*swld_radius	Display spotwelds using the PANEL gap, TRUE radius or a FIXED radius (PANEL, TRUE, FIXED)
d3plot*swld_panel_factor	Factor to multiply PANEL gap by when drawing spotwelds spheres
d3plot*swld_true_factor	Factor to multiply TRUE radius by when drawing spotwelds spheres
d3plot*swld_fixed_size	Default radius used when drawing spotwelds with a FIXED radius
d3plot*swld_scale_by_value	TRUE if spotweld radius is going to be scaled by the value
