Creates parameters that you can link to model dimensions, global
variables, materials, and features from Simulation or Motion studies. You can also edit or
delete existing parameters.
You can use parameters in Design Studies and link them to variables
that can be changed with each iteration of an evaluation or optimization design
scenario.
To access the Parameters dialog box, click.
You can also view defined parameters in the Parameters node of the Simulation study tree.
Name |
Enter a parameter name. |
Category |
Selects the parameter type from one of the
following options:
Model dimension
|
Linear, angular, or pattern
instances
|
Global Variable
|
Define global variables in the Add Equation dialog
box.
|
Simulation
|
Study properties, Mesh, Loads, Fixtures,
Shells, Contact
|
Material
|
Material of single-body or multi-body
parts
|
Motion
|
Study properties, Motors, Springs and
Dampers, Contact
|
|
Value |
Shows the numeric value of the
parameter. |
Comment |
Shows descriptive information
about the parameter. |
Linked |
Shows an asterisk
*, when the parameter is linked to a
component. |
Properties
Value |
Enter a numeric value of the parameter. For a Model
Dimension type parameter, the admissible range
for length is: from 1e-08 m to 1e +24 m for the SI unit system.
You can modify the unit of the Length type in .
|
Expression |
Select to enter an expression that defines the
parameter. You can use a combination of operators, mathematical
functions, constants, or previously defined parameters to define an
expression. The units of the expression
must be compatible with the defined parameter. For example, if
you defined p = 50 psi, and A = 5 cm2, then you can properly define a force F = 3*P*A. It is
not correct to define F with dimensionally incorrect terms such
as A, 5*A2 , P, P2 , or P/A.

Units |
Select the units for the numeric value of the
parameter. The list of available units is filtered according to the
selected feature. |
Comment (optional) |
Enter additional descriptive information about the
parameter. |

Item Selection |
Select a feature from the
Simulation or Motion tree to link to the parameter. You can select
more than one feature of the same type to link to one
parameter. You can also link similar
features from different studies to one parameter. For example,
you can link one parameter to the magnitude of Force 1 in study
1 and also the magnitude of Force 2 in study 2.
For a material parameter, select the bodies
(from single-body or multi-body parts) whose material will be
set as a variable in a design study.

Component Link |
Filters the available components according to the
selected feature in the Simulation or Motion tree. Select the
component from the list to link to the parameter. |
