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 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.

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.
  - 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.
    - Add a Stochastic 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 Stochastic approach.
    - Evaluate
      Run the approach.

      - Parallel Coordinate Post Processing
        Visualize data trends.
      - Distribution Post Processing
        Analyze distributions of run data.
      - Scatter Post Processing
        Analyze dependency between two sets of data.
      - Scatter 3D Post Processing
        Analyze dependency between three sets of data.
      - Ordination Post Processing
        Visualize dimension reduction.
      - Data Sources Post Processing
        Analyze data sources.
      - Pareto Plot Post Processing
        Plot the effects of input variables on output responses in hierarchical order (highest to lowest).
      - Reliability Post Processing
        Lookup reliability values.
      - Reliability Plot Post Processing
        Visualize representations of system reliability.
    - Create Reports
      Package reports for data generated during the approach.
  - 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.

Reliability Plot Post Processing

Visualize representations of system reliability.

Visualize Representation of System Reliability

Visualize the representation of system reliability in the Reliability Plot post processing tab.

From the Post Processing step, click the Reliability Plot tab.
Using the Channel selector, select the channel(s) to plot.
Analyze the plot.

The relationship between the desired threshold and the reliability of the system is plotted.

Refer to the vertical axis to locate a desired reliability and find the corresponding x-axis value of the curve to identify the required threshold. For example, "To have 95% reliability I would have to design this value." You can also find a threshold from the x-axis and locate the corresponding reliability. For example, "91% of my designs are below X value". The latter use case is more common.
