Enhancements in ANSA
- Model Browser
Model Organization: It is now possible to save in DM "Subsystem folders" that have "INCLUDE" references to other subsystems. This enhancement facilitates the model organization in cases where an assembly, e.g. a vehicle BiW model, needs to be handled as a single include for some disciplines, but needs to be split down to more includes for some others.
- Data Management
For DMs that support Library Items through their dm_structure.xml, it is now possible to save such Library Items to DM directly from within the Model Browser's Loadcase and Simulation Model tabs.
From Includes to Model Browser: This plugin is a tool that facilitates the migration of a FE model organized with includes to a model organized with Model Browser containers and prepares the infrastructure for modular assembly with the "Smart Assembly" methodology. The tool will guide the user through an includes-labeling process, in order to map each include to the appropriate Model Browser container with the minimum effort. Combined with data management functionality, the tool enables the direct copy of the original include files in the data repository with appropriate metadata, and in this way facilitates the comprehensive management of the migrated model in a modular manner with a data management backbone.
Mapping - SOL200 FE Update: The Plugin now supports optimization results from EPILYSIS, regarding Orientation angle of orthotropic (MAT8 and MAT2) materials on shell elements.
Interior - FMVSS201U: A new option "Use distance to hard parts" is now available. With this option the tool takes into account the Contact Point - Hard Parts distance. The best Horizontal position of the head is estimated by calculating the distance between the contact point and the hard parts (if any) along the X-axis of the head. Moreover, when the option is enabled, the horizontal position is re-calculated, until the most optimized Node is found.
Known issues resolved in ANSA
Lists - Modify: Unexpected termination would occur when "F1" or "? " was typed in a column modification field.
- Model Browser
Parts - Replace: When an instance of a multi-instantiated part was replaced, the incoming part would not become an instance of the original part. The removal of the replaced instance from the chain of multi-instances was not a desired behavior. Now, when an instance of a multi-instantiated part is replaced, the incoming part remains an instance of the original part.
- Data Management
Input: When a Model Browser container (Subsystem, Simulation Model etc.) is exported from ANSA, its properties are written both in the DM Header section of the solver keyword file and as ANSA Comments. Mismatch between the properties written in the DM Header and ANSA Comments could lead to the creation of duplicate entities in the Model Browser during Input. The properties written in the DM header now prevail over properties written in the ANSA Comments section.
- Data Management
Subsystems - Save in DM: Excessive time would be taken when additionally saving JT file ("Light Representation" option).
- Connections & Assembly
Modules/Convert: Conversion of FE-entities referenced by different Modules into ANSA connection points would lead to abnormal termination, as well as to ANSA databases prone to get corrupted, once recovered.
Utilities - Deck Info: The function would totally omit RBE2 elements in the calculation of Total Number of Elements.
Checks > Duplicate Elements: The function would not detect 2nd order duplicate shell elements.
Drawing Styles - Fringe: TEMP values on shells and solids would not be displayed.
Database Browser: Presence of ∗PART_MOVE keyword would slow down the performance during editing of cards (e.g. Material, Property, etc).
Enhancements and known issues resolved in EPILYSIS
Enhancements in EPILYSIS
TOPVAR: Topology optimization for orthotropic and anisotropic materials is now supported through the TOPVAR card.
For shell properties of orthotropic (MAT8) or anisotropic (MAT2) material, the optimization of fiber orientation angle (THETA) is also taken into account through the parameter PARAM, TOPTHETA, YES (default). Topology optimization is also available for solid properties of anisotropic materials (MAT9).
Known issues resolved in EPILYSIS
Frequency Response Analysis with large input and frequency domain would lead to increased memory consumption.
Unexpected termination would occur when the laminate option would be set to "BEND" on a PCOMP bulk data entry with "ECHO=PUNCH" specified.
Enhancements and known issues resolved in META
Enhancements in META
Report Composer PPTX: Audio files are now supported.
Script: The new script function meta.plot2d.CopyPasteSomeCurves has been added, that copies curves from a specific page/window/plot and pastes them to another page/window/plot.
Known issues resolved in META
GUI: Resize of docked windows would not work properly since v19.1.0.
FE-Fatigue: Unexpected termination would occur when trying to load multiple scalar results simultaneously.
LS-DYNA: Optimization results from binout files could not be plotted and unexpected termination would occur.
- Identification of Entities and Data
iFunction - Pick Elements: META would cease to respond in case of line elements with properties.
- NVH Calculators
Modal Response & FRF Assembly: FRF component in FRF Assembly tool defined as "Nastran FRF" with punch file in SORT2 format was not read correctly, causing erroneous calculation results.
Moreover, in Modal Response tool, Transient Response DOFs could take into account the DOFs options of the Frequency Response from the corresponding GUI menu option, since v19.1.0.
About BETA CAE Systems V19. In terms of virtual reality, META v19.0.0 comes up with new features in this field, such as the audio support, expanding web collaboration capabilities toward a more progressive level. Banding together Virtual Reality and Collaboration in post-processing, BETA CAE Systems introduces the Collaboration with Audio.
ANSA V19 augments Modular Assembly potential, introducing Connecting Subsystems, facilitating assembling strategies more. Functionality introduced in prior versions for the effective management of modular models has been greatly enhanced, offering new, modern solutions for old problems.
A new graph view in the Model Browser, assisted by the new Connectivity tab, offers a visual representation of the model architecture with information on model connectivity. Furthermore, with the introduction of the notion of the Connecting Subsystems, both widely used assembly strategies are now supported: Organizing the simulation model with a single connecting include or with multiple connecting includes, one between each pair of modules, is now only a matter of preference. The "Smart Assembly" methodology has built-in support for Rigid Patches for intermodular connections for LS-DYNA models.
The new functionality of modular model build based on reduced representations is introduced for the creation and management of reduced representations of subsystems, directly through Model Browser. Bottlenecks such as the modal model components handling and constraints such as the interaction with full FE components are addressed.
From concept design to final testing, model optimization has been a necessity that undergoes any typical CAE workflow process. The setup, run and inspection of design of experiments real-time results is improved with the new Optimization tool, automating tasks, accelerating the simulation process and minimizing cost and time to market.
