Create Member Mesh

Use the Member Mesh tool to create 1D elements on edges, free lines, nodes, or members.

1. From the 1D ribbon, click the Member Mesh tool.

   
   
   Figure 1.

   Note: The Member Mesh tool is in a tool group with Stiffener Mesh. Click the arrow to the right of the icon to cycle between the two.
2. On the guide bar, use the first selector to choose either Lines, Members, or Node List.
3. Set or change meshing/orientation/organization options by clicking on the guide bar.
4. Select source entities.
   When you select lines, there is an automatic sort according to the following rules:
   • Free lines – all lines are meshed as though the line mesh panel was behaving with default orientation derived from the line's Frenet frames.
   • Unmeshed edges – seed based on size/density/biasing like orphan lines, but default orientation follows the local surface normal.
   • Meshed edges – meshing behavior depends on the value of the Reference shells option:
     • None: sample elements along lines based on mesh size/density. Orientation depends on options.
     • Displayed: seed element along shell edges irrespective of density/size set. Orientation and offset derived from displayed connected shells.
     • All: seed element along shell edges irrespective of density/size set. Orientation and offset derived from all connected shells.
   For edges and nodes, mesh is honored if the reference shells option is set to displayed or all. If it is set to none, mesh density is honored even if there is shell mesh.

5. Select meshing parameters and biasing options.
   1. In the microdialog, use the icon drop-down menu at the top-left to define mesh by either size or density and then input a value.
   2. Select an engineering type of elements to create BEAM, ROD, or PIPE.
      Depending on the solver profile, you may have a provision to select a solver property card image.
6. Optional: Create bar3 or bar2 element when it applies.
   Note:

   • If mesh follows shell edges, the order is given by the adjacent shells.
   • If mesh is done on free lines, elements bar2/3 are created based on this selection.
   • This option is not available in all solver profiles.
7. Optional: Select an orientation vector and apply it to all newly created elements.
   • Click in the microdialog to orient using the Vector then click . After defining the orientation vector, press Esc to return to the current tool.
   • If neither of the icons are activated, the orientation will follow default orientation. This may vary based on the solver profile.
8. Optional: Using the second selector on the guide bar, assign either a property or beam section to the selected elements.
   See the Restrictions below.
9. On the guide bar, click one of the following:
   • - Save changes and stay in the tool.
   • - Save changes and close the tool.
