The MBx Interoperability Forum is significantly improving STEP translator quality and decreasing translator time-to-market
CAE User Group

CAE domain overview

The CAE-IF is a sub group of the MBx-IF dedicated to the implementation and testing of the STEP AP209 standard. It focuses primarily on the Finite Element Analysis (FEA) in the Mechanical domain for Linear Static Analysis. Other domains (such as Dynamics analysis or CFD for instance) will be addressed later.

CAE Implementor Group and CAE user group:
The Implementor Group is composed of CAE developers and vendors implementing AP209 translators and running the CAE test rounds, while the user group is representating the industry needs.

For more information, please contact :


Regarding the CAE-IF, the user group is mainly in charge of :
- defining business scenarios,
- prioritizing functionalities to be tested and define/update the CAE-IF roadmap,
- defining test cases and validation criteria.
The "Round trip process" (as represented hereafter) is the first business scenario to be considered, applied to a vehicule level model, in the context of the Long Term Archive and Retrieval (LOTAR) needs.

CAE Round Trip process

The CAE-IF user group is currently composed by the LOTAR Engineering Analysis and Simulation (LOTAR EAS) workgroup members.

CAE-IF roadmap

In order to reach this goal, the CAE-IF road-map has been set up considering 3 axes : functionality, complexity, process.
  • The first axis will explore all the elementary FEA functionalities, generally using unit test cases. The main functionalities have been listed hierarchically
  • When addressing the complexity axis, the test cases will combine different elementary FEA functionalities, with an increasing model size
  • The process axis will explore different parts of the "round trip process", until being able to run the overall process.
