Description

Drapes plies using the kinematic draping. See the Kinematic Drape topic for additional details.

Inputs

entity_type

The type of entity to drape. Valid value is plies.

mark_id

Ignored for kinematic draping. Set to 1.

application=<value>

The name of the draping solution to use. Valid value is kinematic_draping.

ply_id=<value>

The ID of the ply to drape.

seed_point_x=<value>

The x-coordinate of draping seed point.

seed_point_y=<value>

The y-coordinate of draping seed point.

seed_point_z=<value>

The z-coordinate of draping seed point.

draping_direction_x=<value>

draping_direction_x=<value>

draping_direction_y=<value>

The y-component of vector describing draping direction.

draping_direction_z=<value>

The z-component of vector describing draping direction.

draping_normal_x=<value>

The x-component of surface normal vector at seed point location.

draping_normal_y=<value>

The y-component of surface normal vector at seed point location.

draping_normal_z=<value>

The z-component of surface normal vector at seed point location.

elem_size=<value>

The length of the element edge in resulting draping mesh.

locking_angle=<value>

The shearing angle after which material is considered to be locking.

relaxation_angle=<value>

The relaxation angle for the material.

quadrants=<value>

Default value is ‘yes’. If set to ‘no’, draping analysis will produce cross shaped draping pattern from seed point in given draping direction and transverse direction.

continuations=<value>

The valid values are ‘yes’ and ‘no’ (default ‘yes’).

directions=<value>

Defines combination of 4 possible primary directions in which draping will proceed from seed point. Valid value is integer in range 1-15 (default 15).

projection=<value>

Valid value is 0.

closest_elem=<value>

The ID of element that is closest to given seed node. This parameter provides alternative input for draping direction. If the draping direction is defined as 0,0,0 ply 1 direction from closest element will be used as draping direction instead.

surface_approx=<value>

Valid value is ‘default’.

Example

To drape ply with ID 1:

*plydrape plies 1 application=kinematic_draping ply_id=1 seed_point_x=0 seed_point_y=0 seed_point_z=0 draping_direction_x=0 draping_direction_y=0 draping_direction_z=0 draping_normal_x=0 draping_normal_y=0 draping_normal_z=1 elem_size=1 locking_angle=55 relaxation_angle=3 quadrants=yes continuations=yes directions=15 projection=0 closest_elem=1 surface_approx=default

Errors
