Mechanical


Attach/Replace Geometry

Once you attach a geometry, or for a system that already includes a geometry, the Replace Geometry option replaces Attach Geometry enabling you to replace an existing geometry.

• From Mechanical, the new option Attach Geometry, available from the Geometry object toolbar, enables you to import a geometry from with the application.

Mechanical

• You can apply multiple transforms to a part. The transforms are applied in the order they appear in the tree.

• You can reorder the transforms by drag-drop in the tree.

Mechanical


Restart Controls For Nonlinear Adaptivity Analysis

Harmonic Response analyses.• Specify solution combinations as either Linear or SRSS (Square Root

of Summation of Squares).• Use Tabular Data or a result Set Number to specify which combination

you wish to display.• Import and/or Export the Solution Combination Worksheet as a Comma

Separated Value (CSV) file.

Mechanical


Keyframe Animation for Results

• Keyframe animation enables you to string together different

snapshots of the model in the Geometry window to create an

animation

• Keyframes are created by positioning the model in the desired

orientation and clicking on Create Keyframe.

• The application interpolates the transition from keyframe to

keyframe to create a smooth animation.

• Export the video in various formats:

MP4, WMV , AVI and GIF

Mechanical


• Keyframe animation for Results enables stitching

different snapshots (different view settings) of the model

for smooth visualization of results, coordinating the

animation in time/steps space (natural for results) with

the one in the 3D space (natural for keyframe

animation).

• This can be enabled by clicking the keyframe animation

icon in the animation toolbar and the user can have a

choice of synchronizing the frame rate similar to the one

set in the keyframe animation window

Frames Synchronized with Keyframe animation

Keyframe Animation for Results

Mechanical


Result Section Output

• A result section is a user-defined surface that can be used to output and monitor section forces, moments, heat flow, current, mass flow, and pore fluid volume flux during a solution.

• Result section output quantities (like bending moments and axial forces etc. ) can be monitored without storing results for all elements for each sub step, which significantly reduces the results file size.

RSMESH automatically creates the result section inside 2-D and 3-D continuum element meshes.

OUTPR,RSFO The section output quantities are written to a single Jobname.SECF text file at a user-specified

frequency

NLHIST Certain result section quantities can also be monitored (or terminated) during solution

General Axisymmetric


General Axisymmetric in WB-Mechanical

• Applicable for 3D Static Structural analysis. General Axisymmetric definition is added under Symmetry folder and when scoped to 2D/Surface body makes the behavior of that Body as General Axisymmetric

General Axisymmetry


General Axisymmetric Definition1. General Axisymmetric (Solid 272/273) introduces Fourier series into interpolation

function to describe the change of displacements in the Circumferential (θ) direction.

2. General Axisymmetric object in mechanical takes Nodal planes input to define number of planes and Coordinate system with Axis input to specify the circumferential direction.

3. The graphics view shows the Axis and Orientation by drawing the line and circle. And it shows the number of nodal planes by showing the transformed geometry in different nodal planes

Solid 272/273 Nodal planes value range from 1 to 12 excluding 2

Axis definition must not cut through the body

General Axisymmetry


Stress shown in all nodal planes when scoped to an edge

Total deformation scoped to All Bodies

General Axisymmetric: Results

1. All regular results can be extracted on the General Axisymmetric body scoping or Mesh. The results shown below are Deformation and Stress which are symmetric in the circumferential direction in the presence of Axisymmetric loading applied in this case

Optimization of Shell bodies

• Shell bodies are also optimized if included in the optimization region, but it is not optimized in the thickness direction

Smoothing Result

• Smoothing result can be added under Topology Density result. It creates Smoothed STL, which can then be used for design validation study

Topology Density result with No Smoothing

Smoothed STL with Move limit = 2

is 0. The STL is

smoothed further

with increasing

value of Move

limit



More Accurate Stress Constraint (19.1)

The solver now uses the elemental mean value of the equivalent (von-Mises) stress when a stress constraint is added. When restricting the maximum stress value of a set of elements, a new technique is applied that approximates the maximum more accurately. The normalized maximum approximation uses an adaptive scaling factor for the p-Norm.

Distributed ANSYS Enhancements

• New features• Now default for all simulations!

• Support for SMART fracture

• Support for prestressed substructuringgeneration pass

• Support for substructuring generation pass restarts

is present

Solvers & HPC



• Scaling when contact is present

• Symmetric contact pairs improved• In previous releases both sets of contact and target surfaces for a symmetric

contact pair would reside in a single domain → Now each pair can be decomposed into different domains.

• MPC contact pairs improved• In previous releases if an MPC and a non-MPC contact pair touched or

overlapped, they would both reside in a single domain → These contact pairs can now be decomposed to different domains.

• Contact pair splitting• CNCH,DMP → Automatically split contact pairs during solution

• CNCH,SPLIT → Manually split contact pairs

• CNCH,MERGE → Manually merge contact pair

Workbench Material Designer


Material Designer


ANSYS Material Designer - Goal

Model and analyze the micro-structure of

Fiber reinforced composite materials Lattice structures

to obtain averaged material data,which can be used in subsequent simulations.

Material Designer


Basic Workflow

Specify

constituent

materials

Computed

material

Material Designer


Homogenization

Material Designer employs the following procedure:

• Model the micro-structure (RVE/unit cell)

• Expose it to a set of load cases

• Extract the (force) results

• Obtain homogenized (averaged) material properties

Material Designer


Parameter Dependence

Materials depend on some parameters:

For instance

● fiber volume fraction

● shear angle

● relative density (volume fraction)

● ...

Generate a variable material that depends on these parameters

Use variable material data in subsequent analyses

Material Designer


Why use Material Designer: Powerful RVE Creation

It has never been so easy to get started with multi-scale analysis to create the following RVEs just with a few clicks and compute homogenized material properties

Material Designer


Why use Material Designer 2: RVEs are parametric

RVE models are parameterized, variations can be run out of the box

Material Designer


Material Designer: Example

Material Steel

Gewicht 7.18 kg Gewicht 35 kg

Material Designer


Computed Material Properties

The following properties can be computed:

• Structural

• Linear Elasticity

• Orthotropic elasticity (Young’s moduli, Poisson ratios, shear moduli)

• Anisotropic elasticity (stiffness matrix)

• Density

• Thermal

• Orthotropic secant coefficients of thermal expansion

• Orthotropic thermal conductivity

• Specific heat

• Remark: for nonlinear

• Put the geometry into Mechanical/SC
