Automatic Exclusion of Special Nodes During Rigid Bolt Realization

HyperMesh automatically excludes special nodes as potential secondary 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:
  • rigid links
  • Rigids
  • Rbe3 nodes
  • boundaries condition
  • IMPDISP
  • IMPVEL
  • IBVEL
  • IMPACC
  • FXBODY
  • Nodes inside the Interfaces with Type2

Property Scripts

  1. prop_type2.tcl

    This script is used while creation of RADIOSS [Type2 Spring] in the Spot panel.

    This script does the following tasks:
    • Organizes the realized weld elements to the respective components based upon the link they are connected to. For example, if a weld is created between comp_1(1) and comp_2(2) it creates a component collector with the name RW^^_<id1_id2> and organizes all the welds created as links between these two components into this collector.
    • Creates the following properties collectors:
      RW^^_<id1_id2>
      This property collector (with the P13_SPR_BEAM in case of R-BLOCK and SectBemSpr in case of R-FIX solver subtype) is associated with it as the card image.
    • Creates sets in the following order:
      I1_M_<id1_id2>
      This contains the main as the FIRST link component ID to which the weld is connected to.
      I1_S_<id1_id2>
      This set contains the node ID of the projected spring element to the above component link as the secondary node N1.
      I2_M_<id1_id2>
      This contains the main as the SECOND link component ID to which the weld is connected to.
      I2_S_<id1_id2>
      This set contains the node ID of the projected spring element to the above component link as the secondary node N2.
    • Creates two interfaces Groups (interfaces) for the spring weld elements created between the same component links by the name
      RW^^1_<id1_id2>
      This references the above created sets that contain the ids of first node NI and first component Link C1.
      RW^^1_<id1_id2>
      This references the above created sets that contain the ids of second node N2 and second component Link C2.
    • Creates a plot named Shear_Normal_Force_Plot with two curves from the Normal Force Function [named RW^^FN_1.0] and Shear Force Function [named RW^^FS_2.5], the values of which are read from the Radiossweld_config.ini file.
  2. prop_radioss_rigidupdate.tcl

    This script is run for all the rigid/rigidlink weld configurations in the Radioss user profile. It creates the sets of all the secondary node ids of the rbodies created during the realization process, and assigns the GRNOD card image to them. It also updates some attributes of these cards.

  3. prop_radioss_rigidbolts.tcl
    The script performs the following tasks:
    • Organizes the SPRING element into a component with the name HM_Bolt_SPRING.
    • Organizes the RBE2 elements into a component with the name Realize#001 (# is a number starting with 2 and increments as 2, 4, 6, and so on).
    • Creates a view with the name radioss_rigid_bolts.
    Note: A new component HM_Bolt_SPRING will only be created if their is not a component with the same name that already exists; otherwise the existing component will be used.
  4. prop_radiosshexa.tcl
    The script performs the following tasks:
    • Organizes the hexas into a component with the name Realize_#001 (# is a number starting with 2 and incrementing as 2, 4, 6 for every new component).
  5. prop_pam_rad_adhesives.tcl
    The script performs the following tasks:
    • Creates TYPE2 interfaces (groups) with the names ADHESIVES_CONTACTS_PID_=_#, which reference the independent/dependent links' main sets, and the nodes' slave sets (# is the ID of the links).
    • Organizes the link entities (components, and so on) into sets with the names MAIN_PART_SET_PID, which in turn are referenced by the above interface groups (# is the ID of the link entity).
    • Organizes the solids' nodes on links into sets with the names SLAVE_NODE_SET_PID_=_#, which in turn are referenced by the above interface groups (# is the ID of the link entity).
    • Creates and assigns a property with the name Adhesive_Solid_Property and the card image P43_CONNECT to the solid component.
    • Creates and assigns a material with the name Adhesive_Solid_Material and card image M59_CONNECT to the solid component.
    • Creates a Failure Model with the name Failure_CONNECT_# and card image FAIL_CONNECT. The curves Adhesive_Solid_Material_YsvsNormalElong and Adhesive_Solid_Material_YsvsTangentialElong are required for the material definition.
    Note: For Radioss versions less than Block100 (Block51 and Block90), HyperMesh creates a property definition with the P14_SOLID card image, and a material definition with the M1_ELAS card image.
  6. prop_rad_acm_shellgapcoating.tcl
    This script performs the following tasks:
    • For each connected link the contact /inter/TYPE2/ gets created and is named TYPE2_CONTACT_PID_<link ID>. The following sets are created and referenced.
      MAINPART_SET_PID_<link ID>
      In this set, which is referenced as the main by the above mentioned contact, the link entities like the component get organized.
      SLAVENODE_SET_PID_<link ID>
      In this set, which is referenced as the slave by the above mentioned contact, the hexa nodes projecting onto the main entities get organized.
    • For each link combination the hexa clusters are organized into separate components and named RAD_SOLID_SPOTWELD_PID_<link1 ID>_<link2 ID>. All components are assigned the following material and property:
      RAD_SOLID_SPOTWELD_DEFAULT_MAT.
      This material is defined as /MAT/LAW59/.
      RAD_SOLID_SPOTWELD_DEFAULT_PROP
      This property is defined as /PROP/CONNECT/.

      The default values are read from uhss_washersolid_matprop.rad in the installation.

    • The heat affected zone elements (washer) are organized into one separate component for each link from the ultra high strength steel material and named RAD_WASHER_PID_<link ID>. All components are assigned the following material and property:
      RAD_WASHER_MAT
      This material is defined as /MAT/PLAS_JOHNS/.
      RAD_WASHER_PROP
      This property is defined as /PROP/SHELL/.

      The material and property values are read from uhss_washersolid_matprop.rad in the installation.
