Mid-surfacing of Casting parts - Challenges and solutions
Mid-surfacing of Casting parts is one of the most challenging and time consuming processes in modeling. Since v18.0 ANSA established new standards and presented a completely new way of treating those parts. The goals that we set are automation, speed and accuracy.
Through this demo we will be able to understand how ANSA meshing functionality handles difficult parts like that. The demo will focus on results fixing, thickness and property assignment, thick areas handling using solids and finally geometry creation.

ANSA pre-processing for CFD
This demonstration is an introduction to ANSA for CFD pre-processing. It starts with the ANSA GUI description and proceeds with a quick example of geometry import, clean up and shell meshing. It concludes with the demonstration of a full volume mesh and solver setup. The session is recommended to CFD engineers who would like to have a quick help in order to get started with ANSA

Non-Linear Multi-Scale Modelling of Composites Using ANSA Tools
The scope of this presentation is to demonstrate a workflow for the Multi-scale modelling of structural components made with Composite materials in ANSA environment. Taking advantage of ANSA Homogenization Tool and Results Mapper the user is able to bridge the gap between process simulation and structural analysis and automatically generate a model for the examination of the microstructural behavior of the composite.
The aim of this case study was to substitute the metallic (aluminum) material of a beam, subjected into 3-points bending, with a Short Fiber Reinforced Polymer (Carbon/Epoxy) to reduce its weight.
With known properties of the constituents, a material with equivalent response was estimated for both the elastic and plastic regions, using Mean Field Homogenization formulations. Afterwards, the fiber orientation from the molding simulation was mapped in the structural model. Both models (metallic and composite) ran in the nonlinear regime resulting in almost identical flexural behavior. Furthermore, the high strain area of the model was isolated and a Representative Volume Element (RVE) was automatically generated in ANSA based on given microstructure information and orientation tensor from the molding analysis. The RVE model was subjected into the boundary conditions (strain) of the macro-scale analysis to examine cases of fiber-matrix interfacial damage.
Finally, the beam made by the Composite Material had approximately half of the weight of the aluminum beam. Although in case of the aluminum and composite beam the material response did not exceed the plastic region, in microscale level fiber matrix debonding was observed at the end of the analysis.

Topological repair of optimized model
Optimization of products varies to achieve optimum mass, volume, size, or even shape. With this evolution of the FEA simulations, engineers can simulate and optimize the possible optimization scenarios.
However, direct results, from the optimization solvers, might produce designs that are not suitable for manufacturing, even with 3D printing. Thus, models generated from optimization analyses need to be repaired manually before forwarded for manufacturing. Consequently, specific tools which will help the user retrieve and repair the FEA optimized model and generate a ready-to-manufacture shape are in demand. BETA CAE Systems provide a complete solution package to completely cover such optimization processes.

Latest developments in meshing of structural parts
ANSA is a standard of meshing quality for many years now. This demo will cover the latest enhancements that concern v19 and v20 releases and will focus on Batch mesh, feature treatments, spotweld meshing and ANSA meshing functionality in general

META post-processing for CFD
This demonstration is an introduction to META for CFD post-processing. It starts with the META GUI description and proceeds with an example of loading the geometry of a model and visualizing the results through the use of cutting planes, isofunctions and flow paths, along with other post-processing tools. It concludes with the demonstration of a fully automated post-processing procedure. The session is recommended to CFD engineers who would like to have a quick help in order to get started with META.
11.40 - 12.10
Modular Run Management in a collaborative environment, for analysts and teams
The modular management of simulation runs, based on the use of include files, is a standard practice for the handling of large assemblies, especially for crash and NVH teams. Traditionally, this process relies heavily on file system operations, especially local file copies. Unfortunately, file copy is the biggest ""enemy"" of traceability. From the moment a file is ""cloned"" in the user's storage space, collaboration and history tracking depend solely on the user's discretion.
How can a system eliminate the shortcomings of the existing implementation without adding any overhead to the daily work of the analyst? How can a data management system help? Which are the collateral gains from the upgrade of the modular management methodology? All these questions and more will be answered in this demo session that will go through the general concepts of data management, modular model organization and model update in ANSA on a use-case coming from the crash discipline.

Surface wrapping and HeXtreme volume meshing for CFD
This workshop will demonstrate the applications of the Surface Wrapping and the HeXtreme volume meshing tools available in ANSA pre-processor. Functionalities like octree preview and leak detection solutions will be illustrated. Live demo of surface wrapping will be performed on a complex geometry, including best practices to improve the generated watertight mesh. In addition, the HeXtreme volume meshing tool will be applied to complete the pre-processing.
The session is recommended to CFD engineers who would like to take advantage of octree tools to streamline the meshing process by minimizing the CAD cleaning operations.
14.30 - 15.00
RETOMO: The new era of segmentation exploiting Machine Learning

Design optimization set up using the new Optimization Tool
This session is a demonstration of new ANSA capabilities on optimization set-up through the Optimization tool. This new tool facilitates DOE and optimization processes. Old and new functionality has been organized into one environment that enables the quick and easy management of design variables, the overview of responses and the definition of design constraints among others. Moreover, designs can be created from various available algorithms and the results can be monitored via plots.
