CFG dyna 72 acm (shell gap + coating)
*filter spot
*style acm 4
*body 0
hex8 1 1
*post prop_acm_coating.tcl
|
|
Description: This realization creates one hexa cluster per connector, and realizes a node to node connection to the linked shell meshes by adjusting it (shell coating). Different patterns are available. This is driven by the number of hexas. The appearance can be influenced via the diameter and the washer layer activation.
This realization uses the prop_acm_coating.tcl property script.
The script performs the following tasks:
| 1. | Organizes the HEXA elements into a set with the name CE_HEXSW_# (# starts with 1 and increments as 1, 2, 3, and so on for every new connector). |

dyna mat100
The dyna mat100 exists in exactly the same configuration with the following additional names:
| • | HC glue structural adhesive |
This is in order to keep the realization names from HyperCrash.
|
CFG dyna 100 mat100
*filter spot
*head
*body 0
bar2 1 1
*post prop_dyna_matnum.tcl
|
|
Description: Creates a BEAM element for the body and plot elements for the head, the plot elements are created for visualization purposes and find operations.
This realization also uses the prop_dyna_matnum.tcl property script.
This script is used while creation of mat100/mat100 (hexa)/mat196 custom config welds in the Spot panel. It does the following tasks.
| • | Organizes the realized weld elements to the respective components based upon the link they are connected to and based upon the realization used. |
If a weld is created as mat100 between comp_1(id1) and comp_2(id2), it will create a component collector with the name C_^_<id1_id2>_BEAM_100 and organize all of the welds created as links between these two components into this collector.
If a weld is created as mat100 between the three components comp_1(id1), comp_2(id2) and comp_3(id3), it will create two component collectors, C_^_1W_<id1_id2>_BEAM_100 and C_^_1W_<id2_id3>_BEAM_100. The suffix is based on the realization type:
Mat100: _BEAM_100
Mat100 (hexa): _SOLID
Mat196: _BEAM_196
This collector is later referenced as the weld element set while creating the groups (contact) definition.
| • | This script will create the following properties/materials collectors: |
| - | M_^<id1_id2>_< MAT100 or MAT196> or M_^_1W_<id1_id2_id3>_<MAT100 or MAT196>: These material collectors are created upon the selection of the configuration type by you with the MAT100 or the MAT196 card. The values for the cards are read from the *.ini file. These material collectors are referenced in the above created appropriate components. |

For mat100 and mat196 a group named C_Contact_Spotweld_<group id> and/or for mat100 (hexa) a group named C_Contact_Tied_Shell_Edge_To_Surface_<group id> is/are created. These interfaces are defined with the appropriate solver cards and reference the following master (MSID) and slave (SSID) sets: |
| - | For the *CONTACT_SPOTWELD_ID card the following FS and FD are set to 0.1. |
| - | For the *CONTACT_TIED_SHELL_EDGE_TO_SURFACE_ID card FS and FD are set to 0.1 as well. Additionally the values for variable SST and MST in the card image are set to 0.010. These values will override the thickness and establish the tied connection. |
| • | The script creates sets by the name C_S_^Part_<set id>_Contact_<group id> and C_S_^Weld_<set id>_Contact_<group id>.

Description: This realization creates a single row of BEAM elements for the body.
This realization uses the prop_dyna_matnum_seamarea.tcl post script and the weld_config.ini and init_dyna_mat196.ini config file.
The script performs the following tasks:
| 1. | Creates ContactSpotweld(interfaces) with the name BEAM_SEAM_CONTACT_PID _#, which references the independent/dependent links' master sets and the nodes' slave sets (# is the ID of the link components). |
| 2. | Organizes the link components into a set with the name BEAM_SEAM_MASTER_PART_SET_PID_#, which is referenced by the above interface group (# is the ID of the link component). |
| 3. | Organizes the beams‘ nodes on the links into a set with the name BEAM_SEAM_SLAVE_NODE_SET_PID _#, which in turn is referenced by the above interface group (# is the ID of the link component). |
| 4. | Creates a component with the name BEAM_SEAM_MAT196_COMP_PID_#_# for the connector BEAM elements (# is the ID of the link component). |
| 5. | Creates a property with the name BEAM_SEAM_MAT196_PROP_PID _#_# and the SectBeam card image, and assigns it to the BEAM component (# is the ID of the link component). |
| 6. | Creates a material with the name BEAM_SEAM_MAT196_MAT_PID_#_# and the MATL196 card image, and assigns it to the BEAM component (# is the ID of the link component). |
|
| Note: | Use the init_dyna_mat196.ini config file to set the default attributes for the created MATL196 material. |

Automatic Exclusion of Special Nodes During Rigid Bolt Realization
HyperMesh automatically excludes special nodes as potential slave nodes for any rigid bodies created during bolt realization, even though they fall with the virtual Bolt Cylinder diameter. Nodes that are shared by the following entities are considered special nodes:
| • | Nodes inside the Interfaces with Type2 |
