PyTwin

Overview

PyTwin is a Python package for consuming a digital twin model that has been exported from Ansys Twin Builder as a TWIN file. Each TWIN file is a self-contained app (twin runtime) that consists of two parts:

• The twin model, which is the simulation model created and compiled in Twin Builder
• The runtime SDK, which is the shared library for consuming the twin model within the deployment workflow.

Because PyTwin wraps a twin runtime in a Python interface, you do not need a Twin Builder installation to deploy it.

For more information on digital twins and Ansys Twin Builder, see Digital Twins and Ansys Twin Builder on the Ansys website.
