Driving efficient design variation studies using ANSYS Electronics Desktop and optiSLang

In this webinar, we present the new custom integration for ANSYS Electronics Desktop (AEDT). The custom integration includes a setup wizard, which lets you establish a running workflow in an instant. This new linkage between ANSYS Electronics Desktop and optiSLang allows to benefit from all the optiSLang algorithms for sensitivity analysis, optimization, and robustness evaluation when driving design variation studies on simulation models implemented in Maxwell, HFSS, Simplorer, Rmxprt, and more in future versions. In the webinar, we will demonstrate how the custom integration handles different groups of AEDT model parameters, how parameters can be filtered, how simulation results are collected for postprocessing in optiSLang, and how the workflow can be switched from serial to highly parallelized simulations exploiting the Optimetrics functionalities of regular and large-scale DSO.

Understanding the model behavior of a thermal-mechanical simulation using ANSYS and SoS

Machine learning, sensitivity analysis and statistical analysis help to understand the behavior of CAE models, the relationships between parameters, the variation patterns of the structural performance and more. SoS helps here to do such analysis on 3D FEM models visualizing the results for many different locations and also analyzing the relations between the different locations in space.
The webinar illustrates the data analysis with SoS using an electrical circuit model in ANSYS Mechanical. Results can be directly exported from ANSYS Mechanical to SoS using the new SoS plugin for ANSYS. Based on a Design of Experiments the FEM results data are visualized and analyzed in SoS. The questions to be answered are:

  • Where are the largest variations of temperature and mechanical stresses?
  • Where are the largest values with a specific probability?
  • What are the most sensitive input parameters for individual locations?
  • How can one create a nonlinear real-time approximation model for the complete FEM solution model?
  • What are the relations between response fields like temperature and stress?

Signal analyses with optiSLang and Statistics on Structures

In CAE – based product development, computed results are often not only scalar numbers, but kind of XY-data. Examples are dynamic signals, spectra, sensor data, or stress-strain-curves. A typical application is the calibration of material law parameters to given measurements.
The functionality of SoS required for the analysis of signals is implemented as a simple, single node in optiSLang. With that, the Field-Metamodel of Optimal Prognosis (F-MOP) is fitted to the signal data. The post-processing displays the F-CoP (Field-Coefficient of Prognosis) and sensitivities of input parameters versus the abscissa of the signal. Thus it is easy to see where in the range the response signal is well explainable and where it is noisy, and to assess which input has dominant influence where in the range of the signal. The F-MOP can be used for optimization in an equally simple way.
During the webinar, the capabilities of optiSLang and Statistics on Structures will be demonstrated by several examples, such as calibration of non-linear material parameters for a concrete wedge splitting test, and other industrial applications dealing with time series and spectra.

Understanding the properties of porous materials using GeoDict combined with optiSLang

Nonwovens, foams, ceramics, and other porous materials become increasingly used as technical materials with unique properties (e.g. lightweight, insulating materials, electrodes). Composite structures often combine several, sometimes contradictory characteristics. Thus, determining an “optimal material“ is a challenging task. The properties assessed by GeoDict simulations are extremely complex and almost impossible to measure in a laboratory. The combination of GeoDict and optiSLang enables an easy and efficient way to create a Design of Experiment. Metamodels of Optimal Prognosis identifies the important input parameter for an optimization of the material properties. Due to the leading-edge Pareto optimization technology of optiSLang, this knowledge can be used to optimize the materials even if there are conflicting objectives (e.g. light and stable).
As an example, the analysis of the particle deposition in a fluid filter made out of fiber material will be shown. These filter will be optimized regarding the efficiency and the pressure drop. With these methodology new Designs can be found, which could be used in a further simulation in one of the  ANSYS CFD Tools.

Optimization and design of turbo machines using ANSYS optiSLang and CFturbo

Optimization in turbomachinery is a challenging task due to demanding numerical CFD simulations. Using sensitivity analysis, meta-modeling techniques and optimization on Response Surfaces will enable you to design turbo machines with acceptable numerical effort. The efficiency of the approach becomes even more relevant when several operating points should be taken into account. The basis for such an analysis is a well parametrized geometry and an automated workflow which will be both presented in this webinar. The parametrized geometry is provided by CFturbo and the workflow is set up in ANSYS optiSLang using different Solvers like PumpLinx and CFX in ANSYS Workbench. As an example, the analysis of a pump and a radial turbo compressor will be presented.

Optimal layout of electric machines using Motor-CAD and ANSYS optiSLang

A linkage between Motor-CAD and optiSLang has been created to provide a world leading optimization procedure for the design of rotating electric machines. Typically, optimization procedures for electric machines focus on evaluating each candidate design at a single operating condition considering only electromagnetic effects, this causes many challenges and often leads to a sub-optimal design.
The Motor-CAD-optiSLang workflow allows engineers to evaluate candidate designs across the full operating speed range, considering both peak and continuous torque/power characteristics, using state-of-the-art electromagnetic and thermal modeling techniques. In addition, the efficiency and performance of considered designs regarding drive cycles can be optimized. Multi-core analysis is used to provide a significant speed improvement to the solution, while the cutting-edge design space analysis techniques contained within optiSLang enable the optimum design to be found quickly and reliably.
