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

All loads on sets are expanded to individual nodes/elements.

Expand sets defined by range

Imports all sets with the GENERATE parameter as regular sets. This is useful when node/element IDs are renumbered during import.

Import Id's

Retains any pre-existing entity IDs during import.

Organize orphan systems, vectors, beamsects into separate collectors

Organizes 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 check box 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.

Read *INITIAL_STRESS_SHELL and *INITIAL_STRAIN_SHELL

These options determine whether to read the *INITIAL_STRESS_SHELL and *INITIAL_STRAIN_SHELL keywords from the solver deck before importing in HyperMesh. By default, both of these check boxes are selected, which results in HyperMesh automatically reading the keywords. If you clear these check boxes, then the data from the *INITIAL_STRESS_SHELL and *INITIAL_STRAIN_SHELL keywords will be exported to a .hmx file.

Map LSDYNA Titles / Headings to HM names

HyperMesh maintains only one name for every solver keyword entity mapped to HyperMesh named entities. This option allows you to 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

This option is only available if the Import as Include option is activated in the Import browser. This option allows you to choose the solver type for the file that you plan to attach as an include to the model loaded in HyperMesh. The following include types are available to choose from in LS-DYNA:

Skip include file in *INCLUDE_STAMP

The include file that is referred using the keyword *INCLUDE_STAMPED_PART or *INCLUDE_STAMPED_PART_SET will be skipped upon import when this option is activated. By default, this option is activated.

Create HM assembly based on includes

This option allows HyperMesh to 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

All of the transformations defined in the model are activated upon import when this option is activated. By default, this option is activated.

ConstrainedExtraNodes_PID_NID

The keywords *CONSTRAINED_EXTRA_NODE_SET, are associated 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

Select this check box to add an ID offset to elements and properties that do not have solver IDs.

Generate Element Property ID's Per Include

Select this check box to 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

Organizes 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 check box is selected, separate System Collectors are created for each Orphaned system.

Element to property ratio

This affects 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:

Delete duplicate nodes

Select this option to delete duplicate node IDs on import; only the final imported node of a given ID will be retained.

Delete duplicate systems

Select this option to 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

Select this option to enable HyperMesh to 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

Organizes 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 ANSA Comments and Read PATRAN Comments

Enables ANSA and PATRAN comments to be read during import.

Element to property ratio

This affects 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:

Delete duplicate nodes

Select this option to delete duplicate node IDs on import; only the final imported node of a given ID will be retained.

Delete duplicate systems

Select this option to delete duplicate system IDs on import; only the final imported systems of a given ID will be retained.

Import comment lines on nodes and elements

Select this option to enable HyperMesh to 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.

Read Engine

Enables you to read the RADIOSS engine cards if an engine file (_0001.rad) is available with the imported input deck.

Read INITIAL SHELL Data

Enables the reading and import process of RADIOSS initial state cards of 2D elements.

Activate transformations

Enables the treatment of 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

Enables the reading and import process of RADIOSS initial state cards of 3D elements.

Create single collector for rigids rbe3 and admass elements

When enabled, one component is created for all rigid bodies and one component is created for all admas elements. When disabled, each rigid body and admas element will be read as a single component.
