Download and use the sample Radioss file (BPillar_Input_Files.zip) to try the DesignAI workflow.
DesignAI allows you to select the primary file for simulation if
there are multiple Optistruct or Radioss input files. The Refresh > Hard Refresh option provides you to select the primary file for simulation from
the list of input files. The Hard Refresh option will purge
the current study data and reset the study to the beginning.
Login to Altair One.
Altair One home page is displayed.
Click DesignAI in the Favorite
Apps.
The DesignAI page is displayed.
The DesignAI page displays the
Study Browser on the left and Design
Study Workflow on the right.
Click the at the bottom of the left pane to
display the list of DesignAI study files.
The Study Browser with the list of DesignAI study
files is displayed.
Click to create a folder.
A New Study 1 folder is created.
Double-click the folder name New Study 1 to rename the
folder name.
Choose one of the following options:
Drag and drop the input file or a folder.
Click the Change link to select the files from
Altair Drive.
The input file that is uploaded is displayed in the Input
Files panel.
If there are multiple input files, then Model Ambiguity
screen is displayed to select the primary file for simulation.
Optional: Select the model file from the Select Primary Model File
drop-down list and click Okay.
DesignAI parses the input file, extracts, and
displays the inputs and outputs of the model.
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.
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.
To enable the curve prediction of an output, toggle the switch of the output to
the right.
Click Execute Simulation.
Notifications are provided at the top displaying the progress of the
simulation. Click to check more information about the simulation
progress.
The Simulations panel also displays the progress of the
simulations.
The Setup stage of the simulation is complete,
and the simulation files are displayed in the Input Files
panel.
