The LS-DYNA R9.0 solver interface is introduced
along with related major keyword updates.
New entity type for *ALE keywords
*ALE keywords are now treated as independent entities, whereas in the
past they were mapped to the Group entity type.
New entity type for *INTERFACE keywords
*INTERFACE keywords are now treated as independent entities, whereas in
the past they were mapped to the Group entity type.
New entity type for *TERMINATION keywords
*TERMINATION is a new keywords, and is treated as independent
entities.
New Keywords
An estimated 70 new keywords have been added, and are part of the
following LS-DYNA keyword groups: *CONTACT; *DATABASE; *ELEMENT;
*INTERFACE; *LOAD; *MAT; *PARAMETER; *SENSOR; *TERMINATION.
Support of *PARAMETER_LOCAL and *PARAMETER_EXPRESSION_LOCAL
LOCAL parameters are now available.
ID Parametrization
*PARAMETER has been extended to the parameterization of ID for the
LS-DYNA keywords created using Component,
Material, Property and Curve entities. The parametrization of the IDs
for those entities is also possible in any keywords where such entities
are referenced.
Mass Summary browser
View model mass, center of gravity, and inertia details in the Mass
Summary browser.
Enhancements
Updated keywords
An estimated 90 keywords have been updated, and are part of the
following LS-DYNA keywords groups: *ALE;
*CONSTRAINED_INTERPOLATION; *CONTACT; *CONTROL; *DATABASE; *ELEMENT;
*EOS; *INITIAL_VELOCITY; *INTERFACE; *LOAD; *MAT; *SECTION; *SENSOR
Penetration Check tool enhancements
The square edges contact option, activated by the SHLEDG or SRNDE
attributes is now considered in the Penetration Check Tool when this
option is enabled in the *CONTACT or *CONTROL_CONTACT keywords.
Model Checker enhancements
The Model Checker infrastructure and functionalities have been improved
for a better user experience.
New checks have also been added.
Removed Keyword 960 user profile
The Keyword960 user profile has been completely removed from the
installation.
Find entities attached to components
The Recursive option has been added in the Find Connectivity tool to
help isolate and find entities attached to selected components. This new
functionality will also help you to automatically find parts until all
connected parts are found.
Removed tool
The following tools, previously accessible in the Tools menu and Utility
browser, are now completely removed from HyperMesh: Set Browser, Create Part, Clone Part,
Material Table, Component Table.
Manage the printing of HyperBeam
messages
An import option has been added to enable or disable the printing of
HyperBeam messages. By default, this
option activated and HyperBeam messages are
not printed.
Export options enhancements
The Export option is now set to Custom by default in the Export
browser.
Resolved Issues
Issue with Model Checker checks related to property and material assignment
to the component, when *PART_COMPOSITE is used.
Reader issue when reading a deck containing
*CONTACT_AUTOMATIC_BEAM_TO_SURFACE.
Issue with reader behavior for the *DEFORMABLE_TO_RIGID keyword. It is also
updated to the R9.0 manual.
Parameter names were exported left justified, but are now exported and right
justified in the parameter name column. This change handles use cases in
which parameter names contain a blank, and the parameter is inside an
encrypted keyword.
Issue with head of edge vector values when creating an infinite plane
cross-section.
Selection of constrained nodal rigid body IDs was not allowed in the
*INITIAL_VELOCITY_RIGID_BODY keyword.
Material direction vectors for composite parts were not being displayed
correctly.
