Major Efforts

Line bodies may now be defined as links. Links have only X, Y & Z degrees of freedom (DOFs) and are often used in truss like structures.

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.

The Fatigue Tool now supports temperature dependent S-N Curves.

Note that the Engineering Data workspace material properties Alternating Stress Mean Stress and Alternating Stress R-Ratio are no longer available properties in the Life category. These have been replaced by the property S-N Curve, along with the new Mean Stress and R-Ratio Field Variables as well as Temperature.

The Solution Information object provides Result Plot Tracker options that enable you to view result contours in real time as the solution progresses. Furthermore, you can add Result Plot Trackers at any point during the solution process.

In the previous release, this feature was only available for Topology Optimization analyses. Now, this feature has been expanded to include Static Structural, Transient Structural, Steady-State Thermal, Transient Thermal, and Explicit Dynamics analyses. New result options include Deformation, Stress, Strain, and Temperature.

The Manufacturing Constraint condition now provides a Scope category of properties in the Details view for the Pull Out Direction, Cyclic, and Symmetry options of the Subtypes property. The scoping options enable you to scope these constraints to bodies and mesh elements, either geometry-based or Named Selections.

The Response Constraint condition now provides a Scope category of properties in the Details view. This category enables you to scope the Local von-Mises Stress Constraint to edges, faces, bodies, and mesh elements. In addition, you can scope the Displacement and Reaction Force constraints to vertices, edges, faces, bodies, and mesh nodes. For element and node scoping, you can specify one or more elements or nodes.

Multiple manufacturing constraints Named selection based constraints

Result histories are now available for the Topology Density and Topology Elemental Density results. This means they can now be evaluated for specific iterations or animated over the solution.

The Iteration property enables you to specify an iteration number.

ANSYS Additive Suite, an add-on product to Mechanical Enterprise level products, is now available to allow simulation of additive manufacturing processes. Transient thermal and a linked structural analysis are used with new AM Process tools built into Mechanical. Auto generated supports can be generated (if required). The process simulation allows simulation of thermal history, structural layer by layer simulation as well as build plate and support removal steps. A wizard is also available to guide users through the process of setting up an analysis. Half built AM part showing results as layers are added

Ease of Use Enhancements

Over 100 new materials from Granta have been included in 19.1.

A range of metals, plastics, woods and other materials have been added in the new "Granta Design Sample Materials" library.

You may also download additional nonlinear materials by visiting the link to Granta's website next to the material definitions in Engineering Data.

Materials folder with properties shown in details view

Mechanical now provides a Materials object. This object contains all of the materials (in object form) available for your analysis. It is also used to insert and specify the following features: Material Assignment (see below) Material Plot Importing Material Fields The new Material Assignment object enables you to assign materials to bodies and while doing so, share the same material ID across bodies in the solver input file.

Animation export formats

Animations can now be exported in multiple file formats. AVI, MP4 and WMV video file types can be created offering more flexibility.

Archived projects can now be imported into existing projects meaning projects can be combined.
