Double-click the DOE component icon  .
The DOE Component Editor appears.
From the DOE Component Editor,
click the General tab.
In the Execution Options area,
click Advanced Options and set the following:
| Option |
Description |
|---|
| Execute designs in random order |
Select this option if you want the design points defined by the design
matrix to execute in random order. Note:
For computer simulations, which are deterministic,
the order of execution has no bearing on the results. This option is
provided primarily for cases in which the design matrix is going to be
exported for use in physical experiments where randomness can alter the
results through the influence of noise (unknown) effects.
|
| Execute subflow only once |
Select
this option if you want to execute the subflow only one time. This capability
is useful in models that need to turn the driver logic on/off parametrically.
This option is also helpful in the debugging process if the model does
not execute successfully. You can map this option to a parameter. For more information,
see Mapping Options and Attributes to Parameters. |
| Read response values from file |
Select this option if you do not want the
DOE component to actually execute an Isight
subflow for each design point but to instead read the response values
for each design point from a specified file. Click Browse
to locate the file. The format of the file must be a first row with parameter
names, with each subsequent row containing the values for the parameters
for that design point. This option is useful when you have a complete
data set (input and output values) already compiled and want to use DOE
as a postprocessing tool. This capability is more directly accessible
using the Data File technique and selecting the File contains
responses option. For more information about this technique,
see About the DOE Techniques.
Note:
For the purpose of storing results in
the results database, the DOE component still makes a call to execute
the subflow for every design point. Therefore, any components that reside
in the subflow are executed (unless they are disabled). Because the intent
of this option is not to require execution of a subflow to obtain outputs,
it is assumed that usually the subflow is empty.
|
| Allow the following items to be turned off
by parameters |
Select this option if you want to turn off
the selected types of design parameters (factors, responses) using input
parameters to the DOE component. If this option is selected, Boolean
input parameters are created in an Active Factors/Active Responses
aggregate under the Mapped Options and Attributes
aggregate parameter. The parameters are selected by default. If any of
the parameters are not selected at run time, those design parameters
will not be used during execution. |
Click Import configuration at runtime
if you want to import the DOE component configuration from a file at
run time.
If selected, Isight
creates an input file parameter on the DOE component called Configuration.
You can point the Configuration file to a specific
file or map it from a file parameter from a previous component in the
simulation process flow. Click  to configure the file
parameter to point to the desired file. You can also configure this file
on the Design Gateway
Files tab. For information about importing/exporting
and the file format, see About Importing and Exporting Configuration Files.
You can map this setting to a parameter. For more information,
see Mapping Options and Attributes to Parameters.
