What's New

R2022x FD01 (FP.2205)

Fully Coupled Procedures

You can now run fully coupled multiphysics simulations using the 3DEXPERIENCE platform.

You run these types of simulations using the newly available procedures, which include:

Coupled thermal-stress
Coupled thermal-stress explicit
Coupled thermal-electrical
Coupled thermal-electrical-stress

These procedures are available for only the general analysis type, which you specify when you open Mechanical Scenario Creation.

The example below depicts a model subjected to thermal, electrical, and mechanical loads. This simulation setup uses the new coupled thermal-electrical-stress step to solve the physics of this scenario.

Benefits: The addition of coupled procedures expands the types of simulations that you can realistically model.

Support for Electrical Physics

You can now define electrical currents and electrical conduction properties (for contact interactions).

The types of electrical currents that you can define include:

Body current
Concentrated current
Surface current

The image below shows each type of electrical current applied to a model. The app indicates a body current using a single, red glyph (left); a concentrated current using a single, yellow glyph (middle); and a surface current using multiple, green glyphs to cover the selected surface (right).

In addition to electrical currents, you can define electrical conduction properties for contact interactions, as shown in the image below.

The app couples the electrical physics with the thermal physics and structural physics (if applicable) to generate your simulation results.

Benefits: Support for electrical physics allows you to simulate problems in which there is joule heating.

Film Properties

You can now define a film property for your thermal simulations.

A film property allows you to define the film coefficient as a function of temperature and field variables. After you create the film property, you can reference it as part of the film condition's definition.

The image below depicts the new Film Property dialog box that you use to define the film coefficient.

Benefits: Film properties allow you to define the film coefficient as a function of temperature and field variables.

For more information, see Film Properties

Improved Organization of Action Bar Options

For all types of analysis cases, some options in the action bar were relocated to new or different sections.

There are new action bar sections named Boundary Conditions and Predefined Fields. All options in the Restraints section were relocated to the new action bar sections or to the existing Loads section. In addition, some options in the Loads section were relocated to the new action bar sections.

Benefits: The reorganization of the action bar options improves your experience navigating the app.

Output Requests for Plasticity Corrections

You can now request Neuber and Glinka stress and strain output for evaluations of plasticity corrections.

The following output variables are supported.


NBSEQ	Neuber equivalent stress
NBEEQ	Neuber equivalent strain
NBPEEQ	Neuber equivalent plastic strain
GKSEQ	Glinka equivalent stress
GKEEQ	Glinka equivalent strain
GKPEEQ	Glinka equivalent plastic strain

Benefits: Neuber and Glinka plasticity corrections provide an estimate of plasticity solution of a model that is analyzed with purely elastic material properties. They use less computation resources compared to running a nonlinear simulation. You can use them in durability analyses for life predictions based on elastic solution and for concept design optimization workflows.

Durability: Verity Fatigue Life Simulation for Spot Weld Sets

You can now define spot weld sets and simulate their useful life using a Verity fatigue simulation.

Benefits: The ability to model fatigue for spot welds is an important aspect of the design process in models where they are commonly used, such as in the bodies of cars and trucks.

For more information, see Defining Spot Weld Sets

Durability: Mean Stress Correction for Weld Fillet Sets and Weld Line Sets

You can now define the mean stress correction for individual weld fillet sets and weld line sets. You can also specify the default method for mean stress correction for either feature.

For example, if the fatigue loading creates cyclic stresses that are mostly compressive, the life of the weld is usually longer than for cyclic stresses that include more tensile effects. In this case, you can select a mean stress correction for the weld to specify predominantly compressive stresses for the weld.

Benefits: Specifying the mean stress correction method for individual weld fillet sets and weld line sets lets you describe more realistic fatigue behavior for welds.

Keyword Editor

You can now take advantage of functionality from the Abaqus keyword interface that is not yet supported on the 3DEXPERIENCE platform.

The new Keyword Editor dialog box lets you add Abaqus keywords, parameters, and parameter values to an analysis case. You can specify the Abaqus features you want to use by defining them in an XML file or in a Python file, and then attaching that document to a keyword edit feature in Mechanical Scenario Creation.

You can define one keyword edit feature per analysis case, and keyword editing is available only for structural simulations. If an analysis case has a keyword edit specified, the app processes its Abaqus keyword functionality when you run the simulation and when you export it to an Abaqus input (.inp) file.

Benefits: The keyword editor enables you to complete additional simulation workflows without leaving the 3DEXPERIENCE platform.

For more information, see Creating a Keyword Edit

R2022x GA

Revised Supports for Element Type Assignments

You can now review and edit element types using the new Element Type Assignment dialog box.

When creating a local element type assignment, you now select a section instead of a mesh part as the support. The element types apply to all mesh parts associated with that section definition. The supports for element type assignments in existing simulations are automatically migrated to use the section corresponding to their mesh parts as their support.

Benefits: Using section definitions for element type assignments, combined with an improved user interface, provides greater flexibility and makes it easier to review and update element assignments.

For more information, see About Element Types Assigning Element Types

Durability: New Durability and Mechanics Engineer Role With Embedded Licensing Using Up to 32 Cores

You can now run structural and durability simulations using the new Durability and Mechanics Engineer (FHM) role, which provides access to embedded licensing with up to 32 cores.

Benefits: Running simulations using this new role provides simulation results faster and can take better advantage of high-performance computing resources.

Durability: Support for Verity™ Solid Weld Line Sets and Line Fasteners

You can now perform Verity weld fatigue life predictions for advanced weld line configurations in solid meshes, and you can select line fasteners as the location where a weld line set resides.

In addition, this enhancement provides a series of model and scenario checks that can help you troubleshoot meshing and modeling problems associated with weld line sets.

Benefits: The improved support for weld line sets lets you simulate weld fatigue life for a wider range of workflows. The troubleshooting enhancements make it easier to resolve problems with the mesh and model so that you can complete the simulation and review the durability results.
