Setting up a Design manager project with Auxiliary files

In this week’s blog post we are looking at how to set up a Design Manager project. We will also be looking at how to provide output files from each design in terms of data tables or pictures, with Auxiliary files, which will save the output in folders corresponding to each design.

How to set up a Design manger project

In the video below you will find how to:

  • Expose parameters in the simulation (NumberOfBlades and ExtrusionDistance is used)
  • Identifying the settings in the base-file that are useful in the design study
  • Creating a Design study
  • Selecting input parameters
  • Selecting responses
  • Settings up Snapshots (scenes)
  • Setting up plots
  • Changing number of cores used
  • Setting the design parameter combinations
  • Run the study
  • Investigating the plots
  • Analyzing the scalar scenes

 

Auxiliary files

When running a Design manager project, running through your combinations of parameters, there is often a lot of data needed to be extracted. Setting up extraction of tables, plot and scenes can be a great way of not needing to evaluate each design via the simulation. By enable the output in the base file, see picture below, you can even use Auxiliary files to get the output sorted per design. In the picture below you see that the output will be saved per iteration, to the specific folder corresponding to the design (indicated by a dot, “.”, to specify the current folder).

In the Auxiliary files output you can choose which type of files to export, see picture below. In the picture, [csv] files are chosen to be exported, but there are also many other formats to choose. Read more about the formats and Run settings in the documentation at Simcenter STAR-CCM+ > Design Manager > Design Manager Reference > Design Studies Reference > Settings Reference > Run Settings Reference.

Note: If you want to run several jobs simultaneously you can utilize one more job per core if you have token (or serial or power session) licenses available. The most economical is to use one token per job, if you have the license structure and computational set up for this option. Set the number of simultaneous jobs in Run settings.

For the output folder structure, visualized in the picture below, you see how the table and other output is saved within each specific folder.
