Major Efforts

At 19.2, the Remote Point object has new scoping options: Remote Points and Remote Points and Nodes. Using these options, you can scope a remote point to one or more other remote points, as well as nodes...

...thereby chaining the Remote Points together. As illustrated in this example, Remote Point 3 is scoped to Remote Points 1 and 2 and its location is defined accordingly.

Topology Optimization Analysis has a number of new capabilities.

Topology Optimization — Linux Support

Topology Optimization is now supported on the Linux platform. All topology features and options are supported, except Geometry modifications for Design Validation (this requires SpaceClaim, which is not supported on the Linux platform).

Topology Optimization — Lattice Optimization

You can now create lightweight parts using optimized lattice structures. The supported lattice types are shown here:

The Optimization Region object, as shown here, provides this new Lattice Optimization option.

Once the Lattice Optimization type is specified, you select the Lattice Type from the seven supported types.

Similar to Topology Optimization analyses, Mechanical automatically inserts density result objects. Supported lattice results include Lattice Density and Lattice Elemental Density:

Topology Optimization — Additive Manufacturing

The Topology Optimization analysis has a new additive manufacturing-based constraint option: AM Overhang Constraint. This constraint enables you to eliminate the use of supports for additive printing for a specified Overhang Angle and Build Direction:

(Requires internet access and will open in a new browser window. Not for Linux platforms.)

Topology Optimization — Loading Conditions

As you can see here, Topology Optimization now supports Inertial and Thermal loads for a Static Structural analysis in combination with a Modal analysis.

Topology Optimization — Analysis Settings

The Topology Optimization Analysis has two new Analysis Settings properties:

• Region of Manufacturing Constraint: This property enables you to specify to Include (default) or Exclude Exclusions. This feature supports the Pull Out Direction, Extrusion, Cyclic, and Symmetry Manufacturing Constraint options. Selecting Include Exclusions satisfies the constraints for the Exclusion Region.
• Region of Min Member Size: This property enables you to specify to Include or Exclude Exclusions (default). Selecting Exclude Exclusions satisfies the Minimum Member Size for the Exclusion Region.

(Requires internet access and will open in a new browser window. Not for Linux platforms.)

There are three additions of note for Substructuring.

Substructuring — Modal Analysis Support

The Substructuring feature now supports Modal analysis. When using the feature with a Modal analysis, the application can automatically detect all boundary conditions (as illustrated below) that exists in the analysis as Condensed Part Interfaces. This includes Joints, Springs, Bearings, Contacts, Remote Points. In addition, you can manually add node-based named selections to these interfaces. Furthermore, you can define the Solver Type as Direct, Supernode, or Subspace. Lumped Mass formulation is also supported and Mass Treatment is now supported for both Point Mass and Distributed Mass.

(Requires internet access and will open in a new browser window. Not for Linux platforms.)

Substructuring — Condensed Part Properties

The Condensed Part object includes three new properties, as illustrated in the Details view example below.

• Generate Damping Matrix: This property enables you to include or exclude damping effects.
• Statistics: This property lists the number of master nodes used for the Generation Pass. This value differs from the value shown for the Number of Master Nodes property of the Interfaces category, whose nodes are modified and the Generate Condensed Part action is not executed.

(Requires internet access and will open in a new browser window. Not for Linux platforms.)

Substructuring — Expansion Pass Worksheet

The new Expansion Pass Worksheet displays once you solve your substructuring analysis and select the Expansion Settings object. With this new Worksheet, you specify the condensed parts for which you want to compute results (Displacement or All Results, including stress and strain). To actually display these results, you must also make the data available in the results file by setting the corresponding Output Controls properties in the Details view to Yes. The properties you can control individually include Stress, Strain, Nodal Forces, and General Miscellaneous. By default, the Stress and Strain properties are set to Yes. If none of these Output Controls properties is active (set to Yes), condensed part results will not display in the Geometry window.

The following example shows Displacement selected for Condensed Part 2 in the worksheet, but not for Condensed Part 3. Looking at the Total Deformation result, we can see the displacement of Condensed Part 2, but not Condensed Part 3.

External Model — ACT Extension

You can now access NASTRAN mesh-based databases through ACT extensions and console window.

Acoustics Analysis — Prestressed Harmonic Acoustics Analysis

Mechanical now enables you to perform a Fluid Structure Interface (FSI) Harmonic analysis using a prestressed structure from a Static Acoustics Analysis. This simulation supports all acoustic boundary conditions and loads that are defined in the downstream system, except the Absorbing Element boundary condition and the Transfer Admittance Matrix and Low Reduced Frequency Model Acoustic Models. All results options are supported.

Ease of Use Enhancements

The New Analysis drop-down menu on the Standard Toolbar includes all the available Mechanical analysis types. When you add a new system through this menu, the Project Schematic automatically updates.

Mechanical now enables you to link and unlink analysis systems, such as Thermal-Stress or Prestressed Modal, from within the application without having to return to the Project Schematic. This new capability automatically creates or deletes the links between the corresponding systems in the Workbench Project Schematic. This feature supports all linked analyses.

Most ANSYS Workbench preferences are now automatically migrated when you install a new version of the application. This includes licensing settings, Options panel settings, solver preferences, and Engineering Data settings.

A new category and property has been added for the Model cell when selected in the Workbench Project Schematic. The new property, License, enables you to specify the license that will be used by a new instance of the Mechanical application for your model.

For thermal analyses, Mechanical now provides the context menu option Create Temperature Results on the Tabular Data of the Solution folder and it enables you to automatically create multiple temperature results based on the selected rows of the Tabular Data window.

You can now delete environments from within the Mechanical application if your Model includes more than one environment. This action also removes the corresponding system from the Workbench Project Schematic.

SMART crack growth enhancements

Back to 19.1 What's New

The Smart Crack Growth object has a new property: Stop At Max Crack Extension. Using this property, you can specify the maximum distance for crack propagation. Once the maximum crack extension limit is reached, the application stops the solution process. In this instance, the solution is incomplete and the Solution folder will not be in solved state because the solution is not complete for all time points. If the maximum crack extension limit is not reached during solution, then the solution process completes normally.
