preface

This course manuaI is based on HyperMesh 7.0, Hyperview 7.0, and ABAQUS 6.4.

HyperMesh is a high_performance finite eIement pre_processor for major finite eIement soIvers, such as ABAQUS.

Hyperview is a compIete post_processing and visuaIization environment for finite eIement anaIysis, muIti_body system simuIation, video, and engineering data.

ln a traditionaI cIassroom setting, this course manuaI wiII heIp you become proficient with various paneIs and utiIities in HyperMesh that set up modeIs for anaIysis with ABAQUS. lt wiII aIso heIp you continue to Iearn about post_processing and viewing ABAQUS

resuIts in Hyperview.

lt is suggested that students have a famiIiarity with HyperMesh and Hyperview before

attending this course. For students unfamiIiar with both software products, the suggested prerequisite HyperMesh and Hyperview course is ModeIing and ResuIts visuaIization

lntroduction. For students famiIiar with HyperMesh, but not with Hyperview, the

suggested prerequisite Hyperview course is ResuIts visuaIization and Data AnaIysis lntroduction.

chapter 1 Foundation for ABAQUS Modeling

ln this chapter, using HyperMesh:

• ABAQUS FE input transIator

• ABAQUS FE output tempIate

• ABAQUS macro menu

• ABAQUS user profiIe

• on_Iine heIp for HyperMesh ABAQUS interface

The above items are the foundation for interfacing with ABAQUS in HyperMesh.

ABAQUS FE lnput Translator

The ABAQUS FE input transIator imports ABAQUS input fiIes. lt is named ABAQUS and it supports input fiIes for ABAQUS versions 5.8 and above. SeIect this input transIator

and import an ABAQUS input fiIe from the fiıes paneI, import subpaneI.

ABAQUS FE Output Template

An ABAQUS FE output tempIate contains ABAQUS_specific formatting instructions that HyperMesh uses to create an ABAQUS input fiIe. SeveraI tempIates exist:

These tempIates are in the foIder ALTA工R-HOME)templates)fe#utput.

SeIect an output tempIate from the fiıes paneI, tempıate subpaneI or the gıobaı paneI. Then begin setting up your modeI for anaIysis with ABAQUS.

The abaqus58 tempIates shouId onIy be used to update HyperMesh binary fiIes

containing an ABAQUS 5.8 modeI. For this case, retrieve the HyperMesh fiIe and then export it using the appropriate abaqus58 tempIate. Then import the exported fiIe into HyperMesh and Ioad the appropriate abaqus 6.4 tempIate. The modeI is now updated to ABAQUS 6.4 and you are ready to begin work on it.

ABAQUS Macro Menu

The ABAQUS macro menu contains six pages of tooIs specific to using ABAQUS with HyperMesh. The Abaqus page contains tooIs specific to interfacing with ABAQUS. The other five pages are the same pages in the defauIt HyperMesh macro menu. The tooIs in the Abaqus page are described in the tabIe beIow.

ABAQUS User profile

Setting the user profiIe to ABAQUS saves you time. Set it from the user prof paneI in the τooı page.

Setting the user profiIe to ABAQUS aIso performs the foIIowing actions:

• Sets the FE input reader to ABAQUS

• Loads the abaqus\standard .3d FE output tempIate

• Loads the ABAQUS macro menu

• Makes the graphicaI user interface ABAQUS focused; some paneI names and paneI options are renamed or removed.

changing the ABAQUS user profiIe to another profiIe, such as optiStruct, does not aIter the ABAQUS modeI.

on_line Help

HyperMesh on_Iine heIp has a reference guide for interfacing with ABAQUS. Access heIp from the heıp button in the permanent menu or press the “h” keyboard key.

on the contents tab in the pop_up window, go to AItair Hyperworks → HyperMesh → ExternaI lnterfacing → lnterfacing with ABAQUS.

chapter 2 lntroduction to Defining ABAQUS Model Data and History Data

ln this chapter, using HyperMesh:

• view images of keywords and data Iines in HyperMesh as they appear in the ABAQUS input fiIe

• create and edit ABAQUS materiaIs and section properties

• SeIect ABAQUS entity types for HyperMesh eIement and Ioad configurations

• create Ioads and boundary conditions for modeI data

• create an ABAQUS step

• Export modeI to ABAQUS formatted input fiIe

section 1: Defining Model Data

HyperMesh card lmages

HyperMesh card images allow you to view images of Keywords and data lines for

defined ABAQUS entities as interpreted by the loaded template. The Keywords and data lines will appear in the ABAQUS input file as you see them in the card images.

Additionally, for some card images, you can define and edit various parameters and data items for the corresponding ABAQUS Keyword.

Use the card (card Editor) panel in the permanent menu to review and edit card images. Also, for many entities, review and edit their card image from the panel in which they are created.

*ELEMENT With section property

The ABAQUS Keyword

大ELEMENT, TYPE = <type>, ELSET = <name>

is defined by ABAQUS elements collected in a HyperMesh component collector. One大ELEMENT Keyword is written to the ABAQUS input file for each element type in the component. The name of the ELSET is the name of the component.

The ABAQUS sectional property associated to the 大ELEMENT is defined by the component’s card image. The material that is associated to the property is defined by a HyperMesh material collector that is associated to the component. The diagram below shows how an 大ELEMENT and its associated property are organized in HyperMesh.

There are more than a dozen component card images for the ABAQUS templates such as SoLıDSECτıoN, SHELLSECτıoN, GASĸEτSECτıoN, BEAMSECτıoN, SPRıNG, JoıNτ and MASS.

Define an 大ELEMENT Keyword with an associated sectional property as follows:

Using the coııectors panel, create a component collector with a card image and a material collector.
lf necessary, edit the component’s card image to define data lines and parameters for the sectional property.
organize elements into the component.

ABAQUS Materials

An ABAQUS 大MATERlAL is a HyperMesh material collector with a card image.

There are three card images for the HyperMesh ABAQUS templates:

ABAQUS-MAτERıAL, GASĸEτ-MAτERıAL (for the Standard templates), and CONNECτOR-BEHAvıOR. There are two methods to create a material collector and associate it to a component. Both methods use the coııectors panel.

Method one

create a material collector with a card image and edit it to define material data. Do this from the create subpanel with coııector type set to mats. Then select this material. when you create a component. The material is automatically associated to the created component.

Method Two

Let HyperMesh automatically create a material collector when you create a component. The material’s name is the component’s name. The material is automatically associated to the component. Then use the card image subpanel to assign a card image to the material and edit it to define material data.

Updating a component’s Material

Update a component with a material from the coııectors panel, update subpanel.

populating Materials with Data

ln HyperMesh, it is possible to add as many data lines as you desire for a material (such as 大PLASTlc with yield stress, plastic strain and temperature data). Manually enter the data in HyperMesh or import an ABAQUS formatted input file on top of the model in HyperMesh to create the data lines.

HyperMesh Entity configurations and Types

HyperMesh element and load entities have two identifiers: configuration and type. The entity configuration is a HyperMesh core feature while the entity type is defined by the

template. For example, some HyperMesh element configurations are rigid, spring,

quad4, and hex8. Possible types of the quad4 configuration in the Standard3D template are S4, S4R, S4R5, M3D4, M3D4R, R3D4 and DS4. Similarly, some HyperMesh load

configurations are constraints, force, pressure, and temperature. Possible types of the pressure configuration in all HyperMesh templates for ABAQUS are DLOAD, FILM,

DFLUX and DECHARGE.

Most of the HyperMesh element and load configurations have their own panels. Use the eıem types panel in the 1D, 2D and 3D pages and the ıoad types panel in the BCs

page to select the desired ABAQUS entity type for different configurations of elements and loads.

ĸinematic constraints in HyperMesh

with the exception of 大EQUATION, ABAQUS Kinematic constraints, such as 大ĸINEMATIC COUPLING and 大MPC (BEAM, TIE, LINĸ, PIN), are rigid (1D) elements in HyperMesh. Create them using the rigids panel in the 1D page. Organize them into HyperMesh component collectors. No sectional property or material is needed for these entities. Hence, either organize them into their own component without a componentcard image or organize them into a component containing different ABAQUS entities.

when Entities Do Not Need a Material

Some ABAQUS entities that are not ABAQUS elements are organized into HyperMesh component collectors. An example entity is 大ĸINEMATIC COUPLING. Such entities do not need a material. when creating a component collector for them, select an existing material to avoid creating one that is not needed.

Unused materials existing in the HyperMesh database will not be written to the ABAQUS input file. An unused material has no card image.

HyperMesh Step Manager for lnitial conditions

The step Manager tool is used to create, edit, review, re_order, and delete ABAQUS initial conditions and steps. This tool is accessible from the Abaqus page in the HyperMesh ABAQUS macro menu. The following image shows its main window.
