Description: Creates hexa element with RBE3 elements projecting and connecting to the surrounding shell elements. This realization uses the shell thickness to calculate the hexa offset from the shell elements. In the case where the model is a 3T connection, the acm (equivalenced-(T1+T2)/2) realization will join the hexa elements.
This realization also uses the prop_nastran_acm.tcl property script.
This script is used in the Nastran and OptiStruct user profiles during the creation of the following configurations:
| • | acm – equivalence/detached –(T1+T2)/2, and shell gap custom config welds in the Spot panel, |
| • | seam hexa adhesive and seam hexa (RBE2-RBE3) in the Seam panel, and |
| • | Area adhesives in the Area panel. |
The script performs the following tasks:
| 1. | Organizes the realized Solid Hexa weld elements created during realization process into components with names based on the realization, such as solid_spot_acm_detached, solid_seam_hexa_adhesive_shell_gap, or solid_area_hexa_adhesive_shell_gap.
Components and the connected RBE’s created as the *HEAD type are organized into components using similar naming, such as rbe3_spot_acm_detached, rbe3_seam_hexa_adhesive, or rbe3_area_hexa_adhesive. |
| 2. | This script creates property collectors, again using names based on the realization such as solid_spot_acm_detached, solid_seam_hexa_adhesive_shell_gap, or solid_area_hexa_adhesive_shell_gap. |
| • | These property collectors are created with the PSOLID card associated with them, and are referenced in the above created components containing the Solid Hexa weld elements. |
| 3. | In addition, this script also updates the weights of any RBE3 that is almost zero, because weight factors close to 0.0 cause Nastran and OptiStruct solvers to generate incorrect results. |
| Note: | New components and properties will only be created if they do not already exist; otherwise the existing components and properties are used. For this reason, comps/props will not always follow the naming conventions given here, because preexisting ones might already have different names. |
Also, when creating realizations with a mid-thickness option, the naming conventions include the presence of the mid-thickness. For example, when creating a hexa (RBE2-RBE3) configuration using a mid-thickness option:
| • | Solid elements will be organized into a Component named solid_seam_ hexa_RBE2_RBE3_mid_thick |
| • | RBE3 elements will be organized into a Component named rbe3_seam_ hexa_RBE2_RBE3_mid_thick |
| • | RBE2 elements will be organized into a Component named rbe2_seam_ hexa_RBE2_RBE3_mid_thick |
| • | Properties will be created with the name solid_seam_ hexa_RBE2_RBE3_mid_thick |
| • | Materials will be created with the name solid_seam_ hexa_RBE2_RBE3_mid_thick |

If there is a direct normal project then an RBE2 elements will be used, if there are only non-normal projections then RBE3 elements will be created. The hexa elements are projected so that they touch the shell elements of the connecting components.
This realization also uses the prop_nastran_acm.tcl property script.
This script is used in the Nastran and OptiStruct user profiles during the creation of the following configurations:
| • | acm – equivalence/detached –(T1+T2)/2, and shell gap custom config welds in the Spot panel, |
| • | seam hexa adhesive and seam hexa (RBE2-RBE3) in the Seam panel, and |
| • | Area adhesives in the Area panel. |

| 2. | This script creates property collectors, again using names based on the realization such as solid_spot_acm_detached, solid_seam_hexa_adhesive_shell_gap, or solid_area_hexa_adhesive_shell_gap. |
| • | These property collectors are created with the PSOLID card associated with them, and are referenced in the above created components containing the Solid Hexa weld elements. |
| 3. | In addition, this script also updates the weights of any RBE3 that is almost zero, because weight factors close to 0.0 cause Nastran and OptiStruct solvers to generate incorrect results. |
| Note: | New components and properties will only be created if they do not already exist; otherwise the existing components and properties are used. For this reason, comps/props will not always follow the naming conventions given here, because preexisting ones might already have different names. |

Description: Creates 1D elements that are constructed out of existing RBAR, CBAR, and CBUSH elements. The outer extensions represent the thicknesses of the outer shell elements. The inner nodes of the RBAR element are connected to the shell elements, whereas the inner nodes of the CBAR elements are coincident to the shell nodes only. CBUSHes are created between the appropriate connected and coincident nodes. Each outer node connects one CBAR and one RBAR. Each HLOCK connection gets its own coordinate system which has a z-axis that is collinear to the HILOCK direction. All affected nodes are assigned to the coordinate system. The coordinate system is taken into account for the DOF definition of the CBAR elements, for the stiffness calculation of the CBUSH elements, and for the DOF of the node constraint.
This realization uses shell properties and materials (PSHELL or PCOMP) and a HILOCK material that you select to calculate the exact position of the outer nodes and the stiffness of the PBUSH elements.
This realization also uses the prop_opt_nas_hilock.tcl property script.
This script is used during the creation of HILOCK custom config welds in the Spot panel from the Nastran and OptiStruct user profile, and performs the following tasks:
| 1. | Organizes the realized 1D weld elements (RBAR, CBAR, CBUSH) created during the realization process into a component named HiLock components. |
| 2. | Creates the following property collectors: |
| • | HiLock_PBAR_<diameter>: This property collector is created with its associated PBAR card. RBAR elements reference this property. Attributes are calculated depending on the diameter specified in the Spot panel during realization. |
| • | HiLock_PBUSH_<translational stiffness>_<rotational stiffness>: These property collectors are created with their associated PBUSH card. The CBUSH elements reference this property. Attributes are calculated depending on the HILOCK material you select and the properties and materials of the connected shells (PSHELL and/or PCOMP). |
| 3. | Creates the following load collector: |
| • | HiLock_SPC6: This load collector is created, and the SPCs created for each HiLock are organized into this collector. |
| 4. | Creates the following system collector: |
| • | HiLock: This system collector is created, and the systems created during the realization are organized into this collector. If the system collector already exists, the newly created systems will be organized into the same collector. |
| 5. | If a HiLock material is not chosen, a default material is created:: |
| • | HiLock_MAT1: This material will be assigned to the PBAR cards, and can be found in the following folder of the installation directory: [hm_scripts_dir]/connectors/HiLock_Mats. |
The predefined values are:
set E 1.8e+07
set G 4.7e+04
set NU 0.330
set RHO 8.9e-09
set A 1.7e-05.
| Note: | This script is called if the realization CFG nastran 111 HILOCK or CFG optistruct 111 HILOCK is used. |
