$D$, $L$, $h$, $t$

#### Parameter definition

VariableDescription
coid Component ID
pid${}_1$ Bolt part ID
default: no bolt
pid${}_2$ Nut part ID
default: no nut
pid${}_3$ Washer 1 part ID
default: no washer
pid${}_4$ Washer 2 part ID
default: no washer
csysid Local coordinate system ID
default: global coordinates are used
tid Optional ID of TABLE with arbitrary number of bolt definitions
default: not used
$D$ Bolt diameter
$L$ Bolt length
$h$ Axial distance between washers
$t$ Washer thickness

#### Description

This command is used to define and position one or more bolts. Multiple bolts can be defined by referring to a TABLE. Each line in the TABLE then contains a coordinate for the bolt location and a vector defining its orientation. An example is given below.

#### Example

Define bolt component with specified position

Definition and positioning of a bolt in a hole. Node ID's $\mathrm{N}_1$=818 and $\mathrm{N}_2$=825 are located on opposite sides on the rim of the hole. The vector between $\mathrm{N}_1$=818 and $\mathrm{N}_3$=225 defines the axial direction of the bolt.

Definition of several bolts using a table

Definition and positioning of 10 bolts using a TABLE. All bolts point in negative $z$-direction. The upper washers are positioned on the upper tool surface at $z=0.052$.
