Topography Panel
Use the Topography panel to define design domains for topography optimization.
Create Subpanel
Option | Action |
---|---|
desvar | Specify a name for the design variable. |
props | Select one or more properties of the selected type. |
Update Subpanel
Option | Action |
---|---|
desvar | Specify a name for the design variable. |
props | Select one or more properties of the selected type. |
Bead Params Subpanel
Option | Action |
---|---|
desvar | Specify a name for the design variable. |
minimum width | Specify the width of the bead at its apex. |
draw angle | Specify the angle of the bead's sloped sides. |
draw height | Specify the height of the bead compared to its parent surface. |
buffer zone | A draw angle exists
between unperturbed nodes in the non-design region and nodes in
the design region. Clear this checkbox to allow an unperturbed
node in the non-design region to be directly adjacent to a
node in the design region which is at full bead
height.
Note: This can lead to mesh quality
problems.
|
draw direction | Specify a draw
direction by clicking the toggle and specifying a direction or a
vector normal to a plane. By default, the draw direction is normal to elements. |
boundary skip | Select a method for
determining which nodes OptiStruct
will leave out of the design domain in order to prevent
perturbation of nodes where loads or constraints are applied.
|
Pattern Grouping Subpanel
Option | Action |
---|---|
desvar | Specify a name for the design variable. |
pattern type | Select a pattern type. |
Bounds Subpanel
Option | Action |
---|---|
desvar | Specify a name for the design variable. |
upper bound | The upper limit for bead growth will be the Upper Bound value times the bead height. |
lower bound | The lower limit for bead growth will be the Lower Bound value times the bead height. |
default initial beadfraction | Specify the percentage of design space where beads are created. |
Pattern Repetition Subpanel
Option | Action |
---|---|
desvar | Specify a name for the design variable |
main / secondary / none | Choose whether you are establishing a main coordinate system, a secondary design variable, or neither. |
system /coordinates | Choose to manually enter the values for the coordinate system, or to graphically select the system. |
global system / local system | Reference coordinate system. |
anchor | Select the anchor node. |
