Altair physicsAI 2023.1 Release Notes

New Features

Visualize Training Results More Easily
Training and validation losses are important metrics to assess the progress of the machine learning training process. The new Model Loss Curve presents these metrics visually in a chart. These charts make it easier to interpret physicsAI trainings.

Continue Training Without Starting from Scratch
The physicsAI training process can take time and having to start over fresh can feel like a waste of time. The restart functionality enables the training process to pick up where it left off. This transfer-learning based technology saves you time whether adding more data to your training sets or re-initiating a prematurely converged process.
Predict a Broader Range of Engineering Results
Not all simulations are 3d fields, such as CFD pressure or structural displacement. Scalar numbers or time history curves can be predicted. PhysicsAI can now be applied to a broader set of design problems that include things like CFD drag or structural contact force.
Access Scalable Computing Resources with Seamless Integration to Altair One
Geometric deep learning requires substantial computing resources for training. Altair One provides workflows to train physicsAI models. Access to the computing power you need is easy with Altair One’s scalable HPC and cloud resources.

Enhancements

  • Reduced time for inference/prediction.
  • Recommended upper limit on mesh size substantially increased from 0.5 million nodes to approximately an order of magnitude larger.
