Use this panel to specify details about hole detection (such as dimensions and feature angles) and bolt realization (including washer layers, number of surrounding nodes, and whether or not to fill holes in 2D mesh).
Panel Usage
There are two separate subpanels, one for hole detection details and one for bolt realization details. You can switch freely between them, or even leave the panel altogether and return, without losing the settings in either one.
| • | Set the panel mode by selecting the subpanel appropriate to the type of edit you wish to perform. |
| • | In the subpanel, use panel inputs to limit the edges that will be edited, or use the default values. These criteria act as a filter so that you can select multiple edges or surfaces but only edit edges that meet certain qualifications, such as proximity to one another or length restrictions. |
Subpanels and Inputs
The subpanels are:
| • | hole detection details: This subpanel allows you to choose the minimum and maximum dimensions for holes to be found, and the minimum and maximum feature angle relative to the surface that the hole appears in. Holes that do not meet these ranges are ignored for functions that relate to bolt holes. This allows you to filter out potential holes and focus only on holes with certain characteristics. |
| • | realization details: This subpanel allows you to specify whether or not to fill holes in 2D mesh, whether to change the nodal density around the edges of holes (and specify a new density if desired), and whether or not to create one or two layers of washer elements and how large the washers should be. |
Panel Inputs
Min dimension =
|
Holes smaller than this are ignored when performing hole detection, as if they did not exist at all.
|
Max dimension =
|
Holes larger than this are ignored when performing hole detection, as if they did not exist at all.
|
Min feature angle =
|
This angle is measured relative to the normal of a solid face; holes with an angle below the specified number (in degrees) are ignored during hole detection.
|
Max feature angle =
|
This angle is measured relative to the normal of a solid face; holes with an angle above the specified number (in degrees) are ignored during hole detection.
|
Fill Holes (2D)
|
This option closes holes in 2D mesh when their bolt connectors are realized.
|
No. of nodes around
|
This option affects the number of nodes seeded around the edge of a hole during realization:
| • | Preserve: no changes are made |
| • | Density: the number of nodes are adjusted to whatever value you specify |
| • | Elem size: The area on the hole edge is remeshed according to the element size that you specify, gaining a corresponding number of seed nodes. |
| • | Auto: HyperMesh decides how many nodes are necessary for the hole to obtain accurate results. |
|
Layer 1
|
Use the checkbox to enable this option, and then choose a method of determining the washer layer size:
| • | Scale (radius): a factor of the bolt diameter. For instance, a scale of 0.5 for an 8mm bolt would create a washer layer that extends 4mm from the edge of the hole. |
| • | Width: Type in a specific width, in whatever measurement units the model was created for. |
|
Layer 2
|
Like Layer 1, but for situations in which realization should create a double layer of washer elements. Use the checkbox to enable this option, and then choose a method of determining the washer layer size:
| • | Scale (radius): a factor of the bolt diameter. For instance, a scale of 0.5 for an 8mm bolt would create a washer layer that extends 4mm from the edge of the hole. |
| • | Width: Type in a specific width, in whatever measurement units the model was created for. |
