Speos for developers


Ansys Speos optical design software uniquely simulates a system’s optical performance and evaluates the final illumination effect, based on human vision. For more information, see Ansys Speos.

Speos APIs (Application Programming Interfaces) offer you the capability to:

  • Access features provided by the Speos for SpaceClaim GUI through the Speos client APIs. 

  • Access features provided by the Speos for NX GUI through the Speos for NX library. 

  • Automate the management of input and output data through the Speos Labs automation APIs. 

  • Automate external simulation through the Speos Core methods. 

The Speos client APIs and Speos for NX library are intricately linked to the GUI, ensuring that the functionalities accessible in the GUI have a corresponding automation function. As the automation functions are directly derived from the GUI, they perfectly align with the actions you would perform in the software, such as creating new Speos objects, editing existing ones, and modifying parameters.  

The Speos Labs automation APIs enable you to perform preprocessing and postprocessing tasks on input data and simulation results from Speos. 

The Speos Core methods enable you to run locally exported simulations from a Speos software or on a network while keeping the Speos software available.
