Design Manager
Design Manager provides an automated approach within Simcenter STAR-CCM+ to run design exploration studies. Design exploration covers both performance assessment and optimization.
- Study Inputs
  In Design Manager, study inputs are parameters that you define in the reference simulation and that Design Manager can modify during design studies.
- Study Outputs
  For each design simulation in a design study, Design Manager allows you to record and write specific outputs.
- Surrogate Models
  In Design Manager, a surrogate is a predictive function that returns an estimated response value for a given set of numerical input parameters. Design Manager computes surrogate functions by fitting data from design study simulations to chosen surrogate models such as Kriging or Least Squares.
- Study Types
  Design Manager offers several types of design study by which you can explore the design space of your product.
- Study Runs
  Design Manager allows you to run design studies on your local workstation or on a high performance cluster. You can run the design simulations sequentially or concurrently, in serial or in parallel. In addition, you can customize the simulation run by inserting Java macros that contain additional setup for the simulation. Design Manager optimizes runs by caching meshes and reusing them where possible.
- Study Analysis
  Design Manager provides post-processing capabilities by which you can analyze the outputs of a design study.
- Design Manager Licensing
  The licenses that are required for running a design study in Design Manager depend on the type of study and the specified run settings. Also, different steps within the Design Manager workflow have particular license requirements.

Input Parameters Properties


Object	Properties
Input Parameters	Parameters Specifies the parameters from the reference simulation to use as input parameters for the design study.
[input parameter]	Parameter Type (only for Sweep, Optimization, Latin Hypercube Sampling DOE, and CAD Robustness studies) Controls how Design Manager sets the input parameter values. Continuous Allows Design Manager to set the input parameter to values within a specified range. This option activates the Continuous child node, which controls the following properties: Range: Specifies the minimum value and the maximum value that Design Manager can set for the input parameter. Baseline Value (only for Optimization): Specifies the value for the input parameter in the baseline design. The baseline design is the first design that Design Manager runs in the design study. Increment (only for Sweep and Optimization): Specifies the increment size. When set, Resolution is automatically updated. Resolution (only for Sweep and Optimization): Specifies the number of different values to look at for the input parameter. When set, Increment is automatically updated. Discrete Sets the input parameter to discrete values. This option activates the Discrete child node, which controls the following properties: Values: Specifies the list of values for the input parameter, separated with commas or spaces. Baseline Value (only for Optimization): Specifies the value for the input parameter in the baseline design. The baseline design is the first design that Design Manager runs in the design study. Constant Sets the input parameter to a constant value, without exploring other values. This option activates the Constant child node, where you set the Value of the constant. Reference Parameter (read only) Displays the associated parameter in the reference simulation. Simulation Effect (read only) Displays the value of the Simulation Effect property of the associated parameter in the reference simulation: Unknown: Implies the parameter affects everything (that is, geometry, meshing, and solver). Geometry: The parameter affects the geometry (which implies it also affects meshing and solver). Meshing: The parameter affects meshing (which implies it also affects the solver). Solver: The parameter affects the solver only. Reference Value (read only) Displays the value of the associated parameter in the reference simulation. Input File Directory Specify the directory of the list of files and only apply to file path study parameter. Lock Name When On, preserves the name of the selected input parameter. When Off, the name of the input parameter is linked to the name of the associated parameter from the reference simulation. When you change the name of the parameter in the reference simulation and update the reference simulation in Design Manager, the input parameter name is updated automatically. Tags Specifies the tags for the input parameter. For more information, see Tagging Simulation Objects.
Factor Value (only for 2-level/3-level full factorial DOE studies)	Factor Mode Controls whether the lower and upper values for the input parameter are absolute or relative to a mid value. Absolute Activates the Absolute child node, where you set absolute values for the lower value (Low), mid value (Mid), and upper value (High). The Mid property is only available for 3 Level Full Factorial DOE studies. Relative Activates the Relative child node, where you set a constant mid value (Mid) and relative low and high values (Low(-%) and High(+%)). The low and high values are relative to the specified mid value.
Distribution Value (only for Robustness and Reliability studies)	Baseline Value Specifies the value for the input parameter in the baseline design. The baseline design is the first design that Design Manager runs in the design study. Distribution Type Specifies the type of probability distribution to use for the input parameter. The probability distribution is centered around the Baseline Value of the input parameter. Normal: Specifies a normal distribution. The standard deviation is specified through the Standard Deviation (%) property in the corresponding child node Relative Normal Distribution. To display a truncated normal distribution, you can specify the following two parameters to limit how far the sample points can deviate from the baseline: Lower Truncation Tolerance: Specifies the lower truncation tolerance relative to baseline with the possible range [0.0, 1e308]. Upper Truncation Tolerance: Specifies the upper truncation tolerance relative to baseline with the possible range [0.0, 1e308]. The truncation tolerance values of 0 indicate the distribution is a standard normal distribution without any truncation. Triangular: Specifies a Triangular distribution. The lower and upper limits of the distribution are specified through the Min Variation and Max Variation properties in the corresponding child node, respectively. Uniform: Specifies a uniform distribution. The maximum variation in either direction is specified through the Max Variation (+/-%) property in the corresponding child node. Weibull: Specifies an one-sided Weibull distribution, which begins at zero. In the Weibull Distribution node, Scale and Shape describe the scale parameter and the shape parameter of a weibull distribution, respectively. Poisson: Specifies a Poisson distribution, which describes the probability of a given number of events happening in a fixed interval of time. The average rate parameter λ defines the curve of the expected number of events in the interval versus the highest probability number of events. A poisson distribution is a discrete distribution with all the variables as integers. Mode Specifies whether the distribution properties (Min Variation, Max Variation, and Standard Deviation) are absolute, or relative to the baseline value. Relative All property values are specified as a percentage of the Baseline Value. Absolute All property values are specified as absolute values.

Input Parameters Right-Click Actions


Object	Right-Click Actions
Input Parameters	Edit... Allows you to create and edit the properties of the input parameters in tabular form except for the study type—manual. For a Manual study, this action opens a Select Reference Parameters dialog, where you can only add or remove input parameters. To edit the properties of the input parameters for a Manual study, you right-click the [design study] > Design Table node and select Edit... .
[input parameter]	Create History Plot Creates a project plot that displays the selected input parameter against the design number. Relink Parameter... Allows you to set the selected input parameter to another parameter from the reference simulation. This option is particularly useful if changes in the reference simulation break the link to the associated parameter. Set New Tag... Creates a new tag and adds it to the selected input parameter. For more information, see Tagging Simulation Objects. Set Tags > [tag] Allows you to set a new tag or a previously created tag to the selected input parameter.
