Perturbations Panel
Use the Perturbations panel to setup shape optimization.
Control perturbations are defined on domain elements to generate shape variables.
Domain Subpanel
Option | Action |
---|---|
node list | Select the nodes
appropriate to the domain elem: type which will be used to
create a domain element. Note: Available in create
mode.
|
domain elem: | Select the type of
domain element to be created. Note: Available in create
mode.
|
domain element | Select the domain
element that you wish to alter. Note: Available in update
mode.
|
highlight and number | Highlight and number
the selected domain element in the modeling window. Note: Available in update
mode.
|
create / update | Select the create or update mode. |
nodeset |
|
out of plane tolerance [0...1] | Include nodes outside the domain element but within a specified tolerance range/distance. The input value for out of plane tolerance must fall in a range of 0 to 1. |
nodes | Select nodes to add to
the domain. Note: Available when nodeset is set to
manual.
|
Perturbations Subpanel
Option | Action |
---|---|
shape = | Specify a name for the
new perturbation shape. Note: Available in create
mode.
|
shape color | Select a color for the entity. Note: Available in create
mode.
|
creation method: | Select the vector
creation method (base and magnitude, two nodes, or cross
product). Note: Available in create mode.
|
base node: | Select the base node on which the perturbation vector is applied. |
global system / local system | Choose whether the vector is created relative to the global coordinate system, or a local system which you must select. |
magnitude = / xcomp =, y comp =, z comp = | Select a method for
defining the magnitude of the vectors.
|
(plane and vector selector) | Specify the vector
direction. Note: Available when the magnitude switch is set
to vector.
|
create / update | Select the create or update mode. |
vectors | Select the existing
vector(s) that you wish to edit. Note: Available in update
mode.
|
vector update method | Select the vector
update method (base and magnitude, two nodes, or cross
product). Note: Available in update mode.
|
Command Buttons
Button | Action |
---|---|
add | Add the selected nodes
to the domain. Note: Available when nodeset is set to
manual.
|
reject element | Undo a newly created
domain element. Note: Available in create mode.
|
reject node set | Undo a newly created
node set. The element remains. Note: Available in create mode,
when nodeset is set to automatic.
|
recalculate | Recalculate the domain. |
create node set | Create a new node set
from the selected domain element. Note: Available in update
mode.
|
create shape | Create a new perturbation shape. |
create vector | Create a new perturbation vector. |
reject | Undo the most recent entity creation. |
animate | Open the Deformed panel, which can be used to post-process the results. |
update | Update the perturbation vectors to use the current settings. |
return | Finalize the permutation and exit the panel. |
