- Pamcrash2G2017 solver profile is introduced, and offers new keywords and major keyword updates related to this new solver version.
- New entity for SECFO keywords as Cross Sections
- SECFO keywords were originally mapped to the Group entity type, but HyperMesh now treats these keywords as independent Cross Section entities with a unique ID, icon and graphics.
- Model Checker
- The Model Checker tool has been added to the PAM-CRASH 2G solver interface, and offers specific checks for solver validity categorized as ERROR, WARNING and INFO.
- New Keywords
- An estimated 35 new keywords are added in HyperMesh 2019. These new keywords are part of the following keywords categorises: PART, MATER, CNTAC, CONTROL, Constraint, SENSOR, SECFO, ELEMENT, PYFUNC, BAGIN-CHAMBER sub-keywords.
- Support of mapping files keywords
- The IMPFIL, IMPORT and EXPORT mapping file keywords with sub-keyword TRANSFORMATION can be created using the Position and Transformation entities.
- Support of picking definition keywords
- The picking keywords PICEXP and PICIMP from 2015 onward and PICK in 2012 to 2014 user profiles can be created using the Position entity.
- New Mass Summary browser
- The Mass Summary browser was added to enable you to review model mass, center of gravity, and inertia details.
Enhancements
- Updated keywords
- An estimated 130 keywords are updated in this new HyperMesh version. These keywords are part of the following keywords categories: PART, MATER, CNTAC, CONTROL, CONSTRAINT, SENSOR, SECFO, SAFETY, ELEMENT, PYVAR, FUNCT, PLOT-OUTPUT, BAGIN-CHAMBER sub-keywords.
- Accurate Mass Calculation
- The mass calculation logic has been improved to match the solver behavior, NSMAS and NSMAS2 accounted as nonstructural mass.
- Pamcrash2G2010-2011 solver interface
- The Pamcrash2G2010-2011 solver interface is removed, but is still available in the installation; however, it will no longer be maintained.
- Removed tools
- The following tools, previously accessible in the Tools menu and Utility browser, are removed from HyperMesh: Set Browser, Create Part, Clone Part, Material Table, Component Table.
- Improved reading and evaluation of Python keywords
- The reading and evaluation of the PYFUNC and PYVAR Python keyword's expressions and IDs have been improved. Complex expressions are not editable in the HyperMesh session, and the expression is not evaluated when its child variables are missing.
- FUNCT enhancements
- Function (FUNCT) supports reference of the python function keyword PYFUNC when FUNTYP is EPYFUN.
- Format of data output
- Data output for all the keywords is right justified except for sub-keyword strings.
- Improved import messages
- Improved import messages with the keywords CNTAC, MATER, Include files, HyperBeam, Airbag sub keywords and so on.
- Removed obsolete keywords
- Obsolete keywords such as RWALL_KIN_CHECK, ADAPT, SUBTA, SOLID4N, SPH and data are unsupported upon import if present in input deck.
- Removed obsolete SPH control card
- Obsolete SPH control card are removed, and the equivalent SPCTRL is available.
Resolved Issues
- Keyword BELTS are mapped to elements instead of beam section collector when using the Entity Editor to select IDNODs.
- Unable to import models that contain Shell and Beam elements that have the same element ID.
- OTMCO supports multiple weight factor on GES when using the Entity Editor to update WEIGHT & DOFCOD.
- Issues related to the creation of INCLU keyword from the Solver Browser.
- Issues with importing/exporting old solver decks that have MATER & SPRGBM keywords handled.
- Issue exporting when GES data has mixed range and is listed under GROUP keyword.
- Issue with FE-Overwrite when working with GES data across keywords (example: BAGIN & PREFA).
- Issue with enabled option in Export browser to write HyperMesh comments into output files.
Altair HyperView
New Features
- Support of Modular ERF (HDF5)
- The ERF reader supports ERF (HDF5) results that use modular input definition.
Enhancements

- The PAM-CRASH ERF (HDF5) and DSY readers have been enhanced to handle higher version result files.
- MPC-PLINK Force
- The MPC-PLINK Force (Global and Local) result type is supported for PAM-CRASH ERF (HDF5) result files.
- ID management

- Femzip version updated to v8.73 for DSY result files.
Altair HyperGraph
New Features
- Support of Modular ERF (HDF5)
- PAM-CRASH ERF reader supports ERF (HDF5) results that use modular input definition. Entity pools for nodes, elements and parts are available to handle duplicate IDs shared across different modules in the same model. These entities will be represented by their module IDs along with their parent entity module IDs.
Enhancements
- Position data type
- Position data type from PAM-CRASH DSY result file is supported.
- PAM-CRASH ERF (*.erfh5) reader option
- The PAM-CRASH ERF (*.erfh5) read option is added to File type filter.
- ID management
- Entity IDs for CNTAC, SENSOR and SECFO keywords are maintained upon reading PAM-CRASH ERF (HDF5) result files.
