Tabs and Inputs
The penetration options window contains tabs for different aspects of the checking tool’s functionality:
Input
|
Action
|
review mode:
|
| • | Transparent non-failed elements displays non-penetrating elements in wireframe mode. |
| • | Gray non-failed elements displays non-penetrating elements in gray color, whether they are in wireframe mode or not. |
|
Penetration Vectors:
|
Select uniform size to keep all penetration vectors identical in length, or penetration depth to draw them with lengths proportional to penetration depth.
| • | If you pick uniform size, type a number into the size filed to set the vector lengths. |
| • | If you choose penetration depth, specify a percent value of their depth. This affects how large the vectors will be drawn on-screen (their numerical values will not change). |
|
label
|
Click the label checkbox to display or hide penetration vector labels.
|
|
Input
|
Action
|
additional offset
|
To add some extra "breathing room" when fixing penetrations, type a value into this field.
De-penetrated nodes will be moved this much farther than the penetration vector when you perform an automatic fix, so that the de-penetrated elements will have a gap between them. In the case of some solvers, this value will also be used to ensure that a gap exists even for elements that touch, but do not penetrate.
|
maximum displacement
|
To limit how far the elements will move when performing an automatic fix, type a value into this field.
De-penetrated nodes will not be moved more than this amount, even if their depenetration vector is longer than this value.
|
Allowable penetration depth
|
To prevent trying to fix elements that have very small penetration depths, type a value into this field.
Nodes with penetration depths smaller than this value will not be moved at all when you perform an automatic fix on their components.
Some solvers do not allow a penetration depth of zero — they require a measurable gap between adjacent surface elements. For these cases, type any negative number into the Allowable Depth field. This signals HyperMesh to automatically move elements that touch each other (but do not penetrate) by the additional offset value (see above).

|
vector
|
Select uniform size to keep all depenetration vectors identical in length, or penetration depth to draw them with lengths proportional to penetration depth.
| • | If you pick uniform size, type a number into the size filed to set the vector lengths. |
| • | If you choose penetration depth, specify a percent value of their depth. This affects how large the vectors will be drawn on-screen (their numerical values will not change). |

Click the label checkbox to display or hide depenetration vector labels.

Input

Action
|
(checkboxes)
|
Choose which columns you wish to display in the tree list. An active checkbox means that the column displays, while an inactive one removes the column from the tree view.
| • | ID is the ID number of the components |
| • | Number of Elems is the number of elemental interactions (penetrations), not necessarily the number of elements in a component or set of interacting components. |
| • | Maximum Penetration Depth indicates the worst (deepest) penetration check result for each component. |
| • | Interacting Components indicates the number of other components that each component penetrates (or intersects, depending on the tree location) but not those components’ ID numbers. |

How do I…
| 1. | On the Penetration tab of the tab area, click the options button. |
The penetration check Options window opens.
| 2. | Ensure that the display tab is in the forefront. |
| 3. | Choose color settings for review mode: |
| • | Transparent non-failed elements displays non-penetrating elements in wireframe mode. |
| • | Gray non-failed elements displays non-penetrating elements in gray color, whether they are in wireframe mode or not. |
| 4. | Choose settings for Penetration Vectors: |
| • | Select uniform size to keep all penetration vectors identical in length, or penetration depth to draw them with lengths proportional to penetration depth. |
If you pick uniform size, type a number into the size filed to set the vector lengths.
If you choose penetration depth, specify a percent value of their depth. This affects how large the vectors will be drawn on-screen (their numerical values will not change).
