BETA-CAE Systems 24.1.0

Combatting model complexity with ANSA

Significant enhancements in model reduction have taken place in v24.1.0, among which the creation of Display Models and Reduced Models directly from Subsystems within the Model Browser, as part of the new Build Process. Coupled with Data Management that has also undergone significant upgrades, Simulation Runs and all their contents can now be recursively deleted through a single operation, provided that they are not used by other DM objects. Moreover, data can now be transferred between DMs with improved robustness and performance with the optimized “Send to DM” functionality.

Sophisticated Meshing algorithms have been introduced in the new release: Automatic identification and fix of intersecting solid structural mesh and on demand creation of compatible mesh on interface areas, as well as Hybrid mesh on casted parts. This Hybrid mesh functionality is coupled the with automatic identification of thick areas and the middle mesh on thin and solid structural mesh on thick areas, hence, leading to top-notch results, coupled with efficiency, and minimized turnaround time.

In a similar manner, placing the focus on CFD, advanced implementations in Layers generation allow for the improved smooth transition between wall function and y+ =1 areas, whereas new options have been added for radially varying first layer height.

In the area of Durability, the implementation of fracture mechanics for Abaqus enables the enriched feature definition for crack propagation simulations with XFEM for shell and solid models. Regarding Composites, Lattice, Porous and Honeycomb RVE FE models can be easily created, set up and homogenized through the RVE Generator.

As VR and AR implementations have been paving the way to XR, Human Body Model Articulation can now also take place in VR, offering positioning of a Human Body Model (HBM), visibility control over layers such as skin, flesh, skeleton, muscles, etc., along with penetration checks.

Closing with User Productivity, the new version is enriched with the power for multiple job submission, executing, monitoring, and controlling in a single window. Other implementations cover the ADVENTURECluster Solver pre-processing interface, for full model setup. This includes boundary and loading conditions, contacts, and analysis type for linear and nonlinear structural and thermal analysis. It is also now possible to automatically translate Abaqus models to EPILYSIS/Nastran and direct submit Abaqus load cases to EPILYSIS.

Significant enhancements in EPILYSIS

The most representative developments in EPILYSIS refer to the calculation of structural intensity flow for transient response for all element types, as well as the support of Modal Participation Factors for MFREQ with AMLS.

Advanced multidisciplinary post-processing in META

Post-processing for CFD analysis has gained significant ground with the implementation of high-quality Cut Planes for models with high order elements, increasing the resolution on high order meshes by cell subdivision. Furthermore, the Interactive Path editing, and Plot update allow for modifications of a Parametric Point Path in real time and automatic synchronization with the associated 2D Plot.

In the field of NVH, the export of Transfer Functions as FMU via Modal Parameter Estimation tool has now become a reality, along with full calculation of the unknown subsystem's Transfer Functions from the full assembly Transfer Functions.

Other discipline-oriented implementations refer to Durability, with the calculation of Abaqus cyclic symmetry deformation results for the whole structure, as well as to Crash and Safety, with the Far Side Virtual Testing Crashworthiness (VTC) .

The new release has also much to offer in the domain of Data Management, composing single and comparison reports, filling presentations templates with values, images, tables stored in Data Management system and significant performance improvements when retrieving data from ASAM-ODS servers.

Furthermore, selected highlights of User Productivity implementations cover the customization of the context menus of 2D Plots, Curves and Axes and the ability to export 3D model and results to Universal Scene Description (USD) format.

Leveraging user experience with KOMVOS

A new KOMVOS Launcher facilitates the retrieval of application settings straight from the central DM Library, along with quick isolation of only data of interest throughout the Database Browser, without the need of specifying any filters.

Moreover, focusing on DM functionality, Subsystem-level Reports enable the storage of validation run under the respective Subsystem and users can compose single / comparison reports filling presentations templates with values, images, tables stored in Data Management system.

Enhanced calculation methods with FATIQ

The new release comes with upgraded FATIQ implementations regarding the analysis for fatigue life estimation of spot-welds. In specific, a dedicated Connection Manager allows for easy definition of spot-welds and automatic recognition from FE results, along with assignment rules for automated material definition on spot-welds.
