Unlock Advanced Parametric Design Options


Parametric design study is a powerful tool that enables engineers to optimize their product designs by analyzing the impact of various design parameters on their product’s performance.

 

Parametric design study

The Parametric Design Options can be explored on the 3DEXPERIENCE platform using the Parametric Design app. This application is available with roles such as Structural Engineer, Structural Performance Engineer, or Structural Mechanics engineer for performing parametric design exploration studies.

This app provides a single platform to perform the study definition, design comparisons, and alternative generation. Using this app, you can perform the Design Improvement Study on the physical product or the simulation object.

While 3DEXPERIENCE process apps such as Process Composer with Results Analytics and Isight perform simulation automation and design exploration offering many functionalities, they require a significant learning curve. The Parametric Design Study app removes that complexity by focusing on the use case of design exploration within a 3DEXPERIENCE simulation object.

Parametric Design Improvement study can be defined for a physical product or simulation object. Design variables are defined to explore the design space and evaluate the response variables such as displacement, stress, or strains. The study automatically calculates feasibility and allows you to compare design points to make optimal design decisions.

You can generate alternatives for one or more selected design points within the Study Results dialog for further analysis or to document design decisions. Each generated alternative has parameter values captured from the respective design point.

If you want a parametric study to reference a physical product/3D part only, create the simulation object directly in the Parametric Design Study app. If you want the study to reference an existing analysis case, create the simulation object in the Scenario Creation app to define the configuration of the analysis case. This simulation object includes containers for the model (product, FEM Rep), scenario (analysis case, study), and results (results of the analysis case and study).

Design variables in a study are input variables. During the design improvement study, the design variables are varied within the defined range to generate the design space.

For SOLIDWORKS users,  design parameters defined in SOLIDWORKS model can be used as design variables. Such parameters can be imported into the 3DEXPERIENCE platform using the Parametric Bridge feature available in simulation or model structure apps as shown in the image below.

For models built on the 3DEXPERIENCE platform, users can select the design variables from geometric knowledgeware parameters, mesh parameters, FEM publications, material properties, loads, or boundary conditions.

Design variables can be selected using the Design Variables Manager or using the Parameter design variable tool.

Response variables define the outputs recorded for each design point in the study. Response variables include Simulation sensor parameters such as stress, strain, displacement, or formula parameters or inertia data such as mass, volume, etc. These can be selected through the Response Variables Manager or defined individually using the Parameter Response Variable tool.

Setting the limits to response variables defines the constraints for the parametric design study. Constraints define the allowable range for a design point to be feasible. Similarly defining an objective function for a response variable sets the object or goal for a response variable.

An objective defines the goal for a response variable value either to be minimized, maximized, or to achieve a specific target. At least one objective needs to be defined for a study to be executed successfully. If needed, you can define multiple objectives, one for each response variable.

Objectives and constraints determine the rank of each design point, which helps the user to choose the design point that meets the design requirements.

The Design Space Check tool is available for use with models built on the 3DEXPERIENCE platform and validates the scope of the analyses planned for a study.  It verifies whether the set of design points can generate a valid model, mesh, and scenario for the study.

When running the parametric design study, users can select the number of design points to be evaluated. Analysis can be run locally or on the cloud.

During the simulation run, you can monitor the results in the Study Results dialog box. The dialog box provides simulation results for each design point after it completes execution.

Once the simulation is complete the results can be viewed within the same interface that provides many post-processing tools and plots options to make informed product design decisions.

Using scatter plots or chart options, you can consider the trade-offs between favorite designs to identify a design direction.

By leveraging the power of parametric study on the 3DEXPERIENCE platform, product designers and engineers can efficiently evaluate the impact of design changes on product performance, identify the optimal design configuration, and make informed product decisions.
