Line Mesh Panel
Use the Line Mesh panel to create a chain of one-dimensional elements such as beams along a line.
Location: 1D page
The Line Mesh panel is used for creating beam models or beam representations of structural models. Line mesh can be created from lines or node lists. Once the selection is complete, click mesh to preview the node seeding of the mesh. It also invokes the density and biasing subpanels, similar to those in the automeshing module, allowing you to interactively modify the element density and biasing.
Line mesh (continuous chain of one-dimensional elements) can be created for a selection of lines or list of nodes (node list).
Panel Options
Option | Action |
---|---|
Lines / Node List | Choose where to create
the mesh.
|
segment is whole line / breakangle = |
|
element size = | Specify a size for the 1D elements. |
element config | Select a configuration
of 1D elements to be created. Note: Each 1D element
can have different types depending on the solver template.
Use the Elem Types panel to set the necessary element type
for the intended 1D element. For example, a spring element
can be used to create a CELAS1, CELAS2, CBUSH, CDAMP1, or
CDAMP2 type of element in Nastran. Line mesh is created with the current element type set
in the Elem Types panel.
For the bars element
configuration, additional options for defining offsets and
orientation are available. |
Offsets | Specify the required
x, y and z offsets for a and b locations. Note: Only available
for bar type element configurations.
|
Orientation | Choose a cross section
orientation for which the bar properties are defined.
Note: Only available for bar type element
configurations.
|
property = | Select an optional
property collector. The 1D elements created (such as bars or
springs) automatically get assigned to these property
collectors. Note: Only valid for solver templates
that define a property directly to 1D elements. Some solvers
such as Abaqus and LS-DYNA allow properties to be defined
only to the components and not directly to the
elements.
|
add elems to current component / add elems to line component | Specify where to organize the 1D line mesh elements after they are created. |
Command Buttons
Button | Action |
---|---|
mesh | Create a 1D line mesh. Secondary panels which can be used to change the density and biasing of the 1D elements are displayed upon clicking mesh. You can interactively adjust the density (and biasing) of 1D elements along a line segment, set the element densities of one or more segments to a specified value, and so on using these secondary panels. |
reject | Undo the most recent meshing action. |
return | Exit the panel. |
