Use the Detach panel to detach elements from the surrounding structure.  You can detach elements from a portion of your model so that it can be translated or moved, or you can offset the new nodes by a specified value.  You can also use this feature to detach and remove elements from your model.

HM_Panels_bmp00085

Elements are selected.

HM_Panels_bmp00086

Elements were detached and offset. Note
that the nodes defining the corner of the
component were not moved.

Subpanels and Inputs

The Detach panel contains the following subpanels:

hmtoggle_arrow1Detach

Panel Inputs

Input

Action

detach elements: elems selector

Select the element(s) that you want to detach from the surrounding structure.

offset new nodes

Choose to offset the detached nodes.

offset =

The amount (in model units) by which to offset detached nodes.

detach all

Detaches any internal nodes attached to the selected elements.
hmtoggle_arrow1Detach From

Panel Inputs

Input

Action

detach elements: elems selector

Select the element(s) that you want to detach from the surrounding structure.

detach from: elems / nodes selector

Select the elems or nodes from which to detach the elements.

offset new nodes

Choose to offset the detached nodes.

offset =

The amount (in model units) by which to offset detached nodes.

detach all

Detaches any internal nodes attached to the selected elements.
hmtoggle_arrow1Detach from wall

Detaches elements from the nodes of wall elements. The elements surrounding the wall can be classified as belonging to different clusters based on which side of the wall elements they appear. For each cluster of elements attached to the wall, the shared nodes are duplicated after detachment.

panel_detach_from_wall_original_model

Original model

panel_detach_from_wall_detach_with_offset

Detach with offset

panel_detach_from_wall_detach_with_offset_and_detached_ends

Detach with offset and detached ends

Panel Inputs

Input

Action

surrounding elements

Select the elements to detach from the wall.

The elements surrounding the wall must be one dimension higher than the wall elements. The elements surrounding the wall can be classified as belonging to different clusters based on which side of the wall elements they appear. For each cluster of elements attached to the wall, the shared nodes are duplicated after detachment.

wall elements

Select the wall elements from which to detach the surrounding elements.

offset new nodes

Offset detached nodes.

offset=

The amount (in model units) by which to offset detached nodes.

detach ends

If enabled, the elements at any free ends of the wall are also detached. If disabled, these elements are not detached from the wall end, but the interior nodes are still detached.

 

 

Comments

HyperMesh creates new nodes at the boundaries of the selected elements and detaches them as a group.  Therefore, the connectivity among the selected elements is not modified by the detach function.
