Setup

Setup data for the simulation using the input file.

1. Login to Altair One.
   Altair One home page is displayed.

2. Click DesignAI in the Favorite Apps.
   The DesignAI page is displayed.

   
   
   Figure 2. DesignAI Page

   The DesignAI page displays the Project Browser on the left and Design Project Workflow on the right.

3. Click the at the bottom of the left pane to display the list of DesignAI project files.
   The Project Browser with the list of DesignAI project files is displayed.

4. Click to create a folder.
   A New Project 1 folder is created.

   
   
   Figure 4. Create Project Folder

   Note: You can also create a group by clicking and create the project folders in the group.
5. Double-click the folder name New Project 1 to rename the folder name.

6. Drag and drop the input file or a folder.
   Note: Click the Take Me To My Files link to view the files in the Altair Drive.
   The input file that is uploaded is displayed in the Input Files panel.

   
   
   Figure 6. Input File for Design Project

   If there are multiple input files, then Model Ambiguity screen is displayed to select the primary file for simulation.

7. Optional: Select the model file from the Select Primary Model File drop-down list and click Okay.

   Figure 8. Select Primary Model File

   DesignAI parses the input file, extracts, and displays the inputs and outputs of the model.

8. All the inputs are selected by default. Click the checkbox next to an input to exclude it from the simulations.
   Note: Click the checkbox next to Label at the top to exclude all the files from the simulation process.

   The inputs from the model file are displayed in this pane. Nominal value corresponds to the values in the input file. Lower and upper bounds for Shell Thicknesses are calculated as +-10% while the lower and upper bounds for Shapes are by default -1, 1. You can change these values by double clicking on them. You can also unselect some of the inputs for the dataset. Based on the selected inputs, the number of simulations that will be performed is displayed in the Simulations panel.

   
   
   Figure 10. Inputs Panel

   The Simulations panel displays the simulations progress and its status. By default, the number of simulations is automatically calculated based on the number of inputs selected by the user. This can be changed by editing the Auto field in this panel. Note that higher values will increase the training dataset, potentially improving the ML model. It is not suggested using less than the Auto value as this will decrease the quality of the ML model.

   By default, the number of concurrent jobs that will run for the simulations is displayed as 10. You can edit the number in this panel. For example, if the total number of jobs to run is 10, you can run 5 at a time as well. When any one of the jobs finishes, the 6th will begin and when another job finishes, the 7th job will begin. This will continue till all the job runs are complete.
