Release Highlights

Unleashing the pre-processing potential in ANSA

The unification of TOPO and MESH functionality, introduced in major v23.0.0, is being further boosted by expanding the unified direct geometry and mesh manipulation to FE entities as well.

Moving on to mesh generation for CFD and aerodynamic analyses, surface wrapping has been enriched with advanced user control on feature capturing per different areas, coupled with optimized performance by using multi-cores. Watertight model preparation has been expedited by new algorithms detecting and isolating interior and exterior areas of complex geometries. New functionality for layers introduces variable first layer height via linear variation or according to flat plate theory.

The Isogeometric Analysis, already introduced in prior BETA versions, is gaining ground with a now greater range of new IGA keywords support, as well as an even more efficient management of the IGA patches.

Getting into the core of the Crash and Safety area, Human Body Models Articulation is being further supplemented with a greater range of postures, along with metadata available for the new diversity models of THUMS family. Moreover, the Bicycle Configurator tool, introduced in the major v23.0.0, now additionally provides I/O of all current angles of each HBM part from/in a JSON file.

As far as the multibody simulations are concerned, Kinetics module now supports quasi-static simulations for running a sequence of equilibrium simulations in time domain, as well as a new type of simulation for calculating the eigenvalues of a dynamic system. Moreover, the embedded beam generator tool provides automated modeling of beam structures and DOF-restrains can now be applied directly on rigid bodies.

Focusing on structural analysis, apart from new patterns for the realization of solid bolts, the direct job submission, already implemented in prior versions for Abaqus, Pam-Crash, and LS-DYNA, has been expanded. Monitoring and error handling is now possible also for Marc, Nastran, Ansys, Optistruct and Permas.

Closing with our latest developments for Electromagnetics, the setup of post-processing electromagnetic results is now a reality via the ASERIS plugin in ANSA.

Boosting optimization calculations in EPILYSIS

The new version offers a significant speed-up in calculations regarding SOL200 optimization with modal frequency response loadcase, combined with AMLS substructuring. The full support of the creation and assembly of modal damping matrices for modal model solutions is also one of the groundbreaking implementations that v23.1.0 comes live with.

Further integrating our solutions in META

Graphics in post-processing are always an asset for META. Towards this direction, in v23.1.0, 360 images and videos can be exported both for desktop and VR.

One of the main implementations the new version provides, is the complete solution for Isogeometric analysis from pre- to post-processing. Geometry and deformation results derived from Isogeometric Analysis elements from LS-DYNA d3plot/d3iga files, can now be successfully read in META.

In the NVH field, v23.1.0 hosts an abundance of noteworthy implementations. The Surface Polynomial Fitting Toolbar provides Zernike modes contributions for disc-shaped deformed structures, whereas the Damping Estimation User Toolbar can be used to Estimate the damping ratio from curves in frequency and time domain. Modal Transient Response can co-simulate with third-party applications via a Functional Mock-Up Interface (FMI). A compact form of an FRF component can now be saved in a metadb resulting in a reduced file and improved I/O performance when used in the FRF Assembly tool. Moreover, User productivity for NVH analysts is further increased through the direct access and navigation to available diagnostic results for top peaks of a specific 2D response.

Consistently placing our focus on various developments in all domains, follow some representative, highlighted cases:

- For Crash & Safety applications, THUMS M50-O and F05-O in Human Body Models Post tool are now supported.

- For Durability applications, Marc HDF format is fully implemented.

- For Molding applications, ESI ProCAST ERF format and Moldex3D solid mesh module for geometry and results have been introduced.

- Laminate information from ANSA comments inside the Ansys .cdb output file can now be retrieved and initial laminate structures can be recreated.

Process design and productivity excelled through KOMVOS

A new feature comes with KOMVOS v23.1.0 which offers the ability to the user to search within Simulation Data using text queries in natural language. On top of that, the Machine Learning Prediction now hosts a brand-new interface with first level view of the predictors KPIs, direct switch between predicted results, and interactive predictions. Additionally, optimal design exploration can be achieved by Smart Sampling, whereas a mode classifier trained with the normal modes result files is now able to generalize and classify the mode-shape types for any FE model.

Streamlining results through SPH solver

Apart from the broader range of applications and the significant speed-up of execution, a plethora of feature-oriented implementations pave the way for more sophisticated processes. For instance, the simulation process has been enriched with enhanced definition of boundary interaction involving the internal adhesion. Mesh can now be generated out of the free surface of the fluid at any timestep and new visualization modes further facilitate result comprehension.
