Solver Import Options

Supported solver import options.

Access solver import options by clicking Select Options, next to Solver Options in the Import - FE Models tab.

Abaqus

Generic material
Import a model in the generic material mode, in which all material sub-options, parameters, and data lines are supported as simple text.
Expand loads on sets
Expand all loads on sets to individual nodes/elements.
Expand sets defined by range
Import all sets with the GENERATE parameter as regular sets.
Tip: This is useful when node/element IDs are renumbered during import.
Import Id's
Retain any pre-existing entity IDs during import.
Organize orphan systems, vectors, beamsects into separate collectors
Organize orphan systems, vectors, and beamsections into a separate collector during import.
When selected, system collectors defined via HMNAME will be honored, and systems organization into particular System Collectors based on their position in the deck will be honored.
An Orphaned system is a system in a master or include file that exists without a HMNAME System Collector in the same include file. Upon import, Orphaned systems are organized into auto generated System Collectors that reside on the same include files as the Orphaned systems. The solver import option Organize unidentified systems into separate collectors controls how the Orphaned systems are organized into the auto generated System Collector(s). When this checkbox is cleared (default), a single System Collector is created and all Orphaned systems are organized into that single System Collector. When this checkbox is selected, separate System Collectors are created for each Orphaned system.
If a property is assigned to the component, then the ID will be stored in the component. In case of indirect assignment the ID will be stored in the property, and in case of another entity the ID will be taken from the corresponding entity.

LS-DYNA

Read *INITIAL_STRESS_SHELL and *INITIAL_STRAIN_SHELL
Read the *INITIAL_STRESS_SHELL and *INITIAL_STRAIN_SHELL keywords from the solver deck before importing in HyperMesh. By default, both of these checkboxes are selected, which results in HyperMesh automatically reading the keywords. If you clear these checkboxes, then the data from the *INITIAL_STRESS_SHELL and *INITIAL_STRAIN_SHELL keywords will be exported to a .hmx file.
Map LS-DYNA Titles / Headings to HM names
HyperMesh maintains only one name for every solver keyword entity mapped to HyperMesh named entities. Choose between the HyperMesh names (if present) in the solver deck as a comment and name present in the LS-DYNA keyword. By default this option is off indicating the preference to the HyperMesh name.
Include Type
Choose the solver type for the file that you plan to attach as an include to the model loaded in HyperMesh.
Restriction: Available if the Import as Include option is activated in the Import tab.
The following include types are available to choose from in LS-DYNA:
  • *INCLUDE
  • *INCLUDE_STAMPED_PART
  • *INCLUDE_STAMPED_PART_SET
  • *INCLUDE_COMPENSATION_BLANK_BEFORE_SPRINGBACK
  • *INCLUDE_COMPENSATION_BLANK_AFTER_SPRINGBACK
  • *INCLUDE_ COMPENSATION_DESIRED_BLANK_SHAPE
  • *INCLUDE_ COMPENSATION_COMPENSATED_SHAPE
  • *INCLUDE_CURRENT_TOOLS
Skip include file in *INCLUDE_STAMP
Skip the include file that is referred using the keyword *INCLUDE_STAMPED_PART or *INCLUDE_STAMPED_PART_SET upon import when this option is activated. By default, this option is activated.
Create HM assembly based on includes
Automatically create assemblies with the name of the include, and the components contained in the include file. The assembly hierarchy data structure also follows the include hierarchy data structure. By default, this option is turned Off.
Activate Transformations
Activate all of the transformations defined in the model upon import when this option is activated. By default, this option is activated.
ConstrainedExtraNodes_PID_NID
Associate the keywords *CONSTRAINED_EXTRA_NODE_SET with the name Xtranodes_PID_NID; where PID is the ID of the *PART keyword and NID is the ID of the Node set ID referenced in this keyword. By default, this option is off.
Extend Element Property Offset
Add an ID offset to elements and properties that do not have solver IDs.
Generate Element Property ID's Per Include
Assign a max ID per Include file, instead of assigning a global max ID to elements and properties that do not have solver IDs.
Organize orphan systems, vectors, beamsects into separate collectors
Organize orphan systems, vectors, and beamsections into a separate collector during import.
When selected, system collectors defined via HMNAME will be honored, and systems organization into particular System Collectors based on their position in the deck will be honored.
An Orphaned system is a system in a master or include file that exists without a HMNAME System Collector in the same include file. Upon import, Orphaned systems are organized into auto generated System Collectors that reside on the same include files as the Orphaned systems. The solver import option Organize unidentified systems into separate collectors controls how the Orphaned systems are organized into the auto generated System Collector(s). When this check box is cleared (default), a single System Collector is created and all Orphaned systems are organized into that single System Collector. When this checkbox is selected, separate System Collectors are created for each Orphaned system.

Nastran

Element to property ratio
Defines how imported elements are organized into components. When importing an FE model and the By HM Comment option is selected but no HyperMesh comment cards exist, Nastran users can specify a ratio to be considered when importing HyperMesh entities. On import, HyperMesh will calculate the ratio of the number of elements to the number of properties:
  • If the calculated ratio is less than the specified ratio, all the elements are put into one component.
  • If the calculated ratio is greater than the specified ratio, one component is created for each property.
Delete duplicate nodes
Delete duplicate node IDs on import; only the final imported node of a given ID will be retained.
Delete duplicate systems
Delete duplicate systems IDs on import; only the final imported systems of a given ID will be retained.
Import comment lines on nodes and elements
Read and store Nastran comment lines above nodes and elements. Reading in models with a large number of comments on nodes and/or elements may increase model import time. By default, this option is turned OFF.
Organize orphan systems, vectors, beamsects into separate collectors
Organize orphan systems, vectors, and beamsections into a separate collector during import.
When selected, system collectors defined via HMNAME will be honored, and systems organization into particular System Collectors based on their position in the deck will be honored.

Read ANSYS Comments and Read PATRAN Comments
Read ANSYS and PATRAN comments during import.

OptiStruct

Element to property ratio
Defines how imported elements are organized into components. When importing an FE model and the By HM Comment option is selected but no HyperMesh comment cards exist, OptiStruct users can specify a ratio to be considered when importing HyperMesh entities. On import, HyperMesh will calculate the ratio of the number of elements to the number of properties:
  • If the calculated ratio is less than the specified ratio, all the elements are put into one component.
  • If the calculated ratio is greater than the specified ratio, one component is created for each property.

Delete duplicate systems
Delete duplicate system IDs on import; only the final imported systems of a given ID will be retained.

Read INITIAL SHELL Data
Read and import Radioss initial state cards of 2D elements.
Activate transformations
Activate Radioss transformations during the import process, so that transformed entities will be displayed in their transformed position after importing the model.
Read INITIAL Brick Data
Read and import Radioss initial state cards of 3D elements.
