New software extentions "Model Reduction inside Ansys"

In close cooperation with Cadfem GmbH, Jade University has enhanced the "Model Reduction inside Ansys" MORiA- today's industrial standard for model reduction of linear finite element models as follows: 1. Stress recovery for reduced order thermo-mechanical models. 2. Implementation of a preservation of Young’s modulus dependency on temperature in the reduced space, for one or more material domains via parametric model reduction. 3. Krylov-based super element and its re-integration in the finite element design flow. 4. Nonlinear model reduction of mechanical models using TPWL.

1. This new feature enhances MORiA's analytical capabilities, allowing for a more comprehensive assessment of structural behaviour. The stress recovery mechanism enables a detailed examination of the distribution and impact of stress across varying parameters, providing engineers and researchers with a more understanding of structural responses.
2. MORIA library is augmented with the successful integration of parametric model order reduction for thermo-mechanical models. This implementation specifically addresses the consideration of Young's modulus dependency on temperature, thereby enhancing the library's capacity to model material behaviour with increased precision in microelectronics reliability field and is an intermediate stage of reducing realistic nonlinear models.
3. A significant extension of the MORIA library through the successful implementation of a Krylov-based super element, seamlessly reintegrated into the Finite Element environment has been achived. This novel addition enhances MORIA's analytical capabilities by leveraging Krylov subspace methods, offering an efficient and scalable approach to address complex structural dynamics. It is now possible to reintegrate a reduced order model into a standard finite element design flow and hence, to pass it along the supply chain without disclosiring the IP.
4. A significant extension of the MORIA library, marked by the successful incorporation of a novel implementation is a nonlinear model reduction using trajectory piece-wise linear approximation. This innovative addition enhances MORIA's analytical capabilities by introducing a sophisticated approach to the generated reduced models. The implementation focuses on capturing the full nonlinear mechanical behaviour through a trajectory piece-wise linear model, providing a nuanced representation of system dynamics.

In order to run the model order reduction software MORiA a licence is required, however the model to be reduced can also be passed in the Matrix Market format. Hence, all users whos design is not based on Ansys tools can still benefit of the new methods implemented within the COMPAS project.
