Perform Studies
A study is a self-contained project in which models, variables, output responses, and approaches are defined.
Setup the Approaches
Once the study Setup is complete, an unlimited combination of approaches can be added to a study. A study approach is a specific set of steps taken to study the mathematical model of a design.
Setup Optimization Studies
An Optimization is a mathematical procedure used to determine the best design for a set of given constraints, by changing the input variables in an automatic manner.
Evaluate
Run the approach.
Review Evaluation Time
Inspect task wall-clock times.

Perform Studies
A study is a self-contained project in which models, variables, output responses, and approaches are defined.
- Setup the Study
  Before you can create approaches you must first setup your Study by defining input variables and output responses.
- Setup the Approaches
  Once the study Setup is complete, an unlimited combination of approaches can be added to a study. A study approach is a specific set of steps taken to study the mathematical model of a design.
  - Setup DOE Studies
    A DOE is a series of tests in which purposeful changes are made to the input variables to investigate their effect upon the output responses and to get an understanding of the global behavior of a design problem. By running a DOE, you can determine which factors are most influential on an output response.
  - Setup Fit Studies
    A Fit is a mathematical model that is trained by data and is capable of predicting output response variables for a given set of input variables.
  - Setup Optimization Studies
    An Optimization is a mathematical procedure used to determine the best design for a set of given constraints, by changing the input variables in an automatic manner.
    - Add a Optimization Approach
      Add approach to the study.
    - Define Definition
      Define the models, input variables, and output responses to be used in the study.
    - Select a Numerical Method
      Select a numerical method to use when evaluating the Optimization.
    - Evaluate
      Run the approach.
      - Run Evaluation
        Select which runs to evaluate and which tasks to perform.
      - Evaluation Parameters
        Modify the run environment settings for the Evaluation tasks.
      - Review Evaluation Results
        Review the input variable and output response values for each run, as well as review the run files.
      - Review Evaluation Time
        Inspect task wall-clock times.
    - Post Processing
      View the computational results from the Optimization.
    - Create Reports
      Package reports for data generated during the approach.
  - Setup Sampling Fit Studies
    A Sampling Fit is a combination of space-filling DOE method and mathematical model trained by the data generated.
  - Setup Stochastic Studies
    A Stochastic approach is a method of probabilistic analysis where the input variables are defined by a probability distribution, and consequently the corresponding output responses are not a single deterministic value, but a distribution.
  - Setup Basic Studies
    A Basic approach can be used to test nominal values and bounds by performing a nominal run, system bound check, or sweep.
  - Setup Verification Studies
    A Verification approach compares two data sets in a side by side comparison.

Review Evaluation Time

Inspect task wall-clock times.

Review the time spent in each task within the Evaluation Time tab. Identify bottlenecks in tabular or plot form.

From the Evaluate step, click the Evaluation Time tab.
Use the top channel selector to select the model(s) to review.

Use the bottom channel selector to identify the time categorises for review.

Option	Action
Write	Time spent in the write task.
Execute	Time spent in the execute task.
Extract	Time spent in the extract task.
Model Total	Total time of the write, execute, and extract tasks.
All Models Total	Summation of all Model Totals. Note: This category is independent of the selected models.

Switch the view between table and plot by clicking or , located above the Channel selector.

Evaluation Time Settings

Settings to configure the plots and tables displayed in the Evaluation Time tab.

Access settings from the menu that displays when you click

(located in the top, right corner of the work area).

Cumulative Rows: Each row entry is a summation of its own wall time and the wall times preceding it with a lower evaluation index.
Plot Time-Unit: Controls the units of time when plotting the wall times.
