Consulting project Types

The ANSYS consulting team specializes in projects that deliver:• Technology transfer or “Jump start” to accelerate

your engineering analysis capability• Process and workflow tuning• Adding functionality to our engineering simulation

tools• Integration of our simulation technology with other

software• Custom solutions that streamline your engineering

workflow


4

Technology Transfer and Jump Start Projects

Projects for new or existing ANSYS users having a specific simulation task, where…• The most effective simulation workflow will be developed and delivered to you• Your simulation expertise needs to be increased and extended in a short time frame• A new user wants to start simulation work on a problem involving a high level of

complexity

SAIPEM Gas Lift Package

SAIPEM is a large international turnkey contractor in the oil and gas industry• Specializes in projects in remote

areas and deep water• ANSYS was asked to develop a

natural convection modelling methodology of the SAIPEM Gas Lift Package

“Our own experience with FLUENT was not sufficient to run efficiently those simulations at the beginning of the project. Therefore we subcontracted this project to [ANSYS]. Now the transferred methodology has been integrated to our internal simulation process. This punctual outsourcing brings several advantages: minimum risk, respect of contractual delivery time, results quality and reliability.”

Fabrice BocatyFlow Assurance Engineer, SAIPEM

• MAN Diesel & Turbo is the world market leader for large diesel engines for use in ships and power stations

• Demand for engine reliability and low life-time service costs brings the need for accurate and careful engineering in the design process

• ANSYS Consulting developed an effective workflow for coupled simulation of Fluid-Structure-Interaction of water-cooled cylinder head

MAN Diesel & Turbo

“We are absolutely pleased how the project was executed. The quality of the results is excellent and we learned a lot.”

Petra SteffeMAN Diesel & Turboin Economic Engineering, May 2008

“It’s a big advantage that the CAE consultant works with the same simulation software as oneself. By that the results can be used for further post-processing without additional interpretation effort.”

Andreas LinkeMAN Diesel & Turboin Economic Engineering, May 2008

Impellor Burst Simulation

• Project for an Existing ANSYS CFD user with a requirement for Explicit Dynamics simulation of an aluminium impellor bursting and hitting it’s casing

• Objective was to reduce time and cost required to introduce new designs, especially testing prototypes

• Solution used an ANSYS Workbench-based workflow:• Steady state thermal calculation of temperature distribution in impellor• Mechanical calculation of stresses in impellor due to 60,000rpm spin speed• Explicit Dynamics calculation of impellor break up and interaction with

aluminium casing

• Deliverables included project workflow and results

Andritz Inc.

• Andritz Group is a global market leader for customized plant, systems and services for the pulp and paper, hydropower and steel industries

• Looking for insight into an equipment retrofit issue• Needed to very quickly come up to speed with ANSYS

FLUENT due to time constraints

• ANSYS engineers setup and solved an initial set of simulations

• Andritz engineers attended introductory training• Worked through their customer-specific example• By the end of the week, Andritz engineers had completed

a first set of simulations• Within three weeks, were able to base engineering

decisions on the simulation results

Workflow Streamlining

Projects involving the development of customized versions of our products that simplify their usage• Examples:

– Simple user interfaces– Templates with embedded best practices– Scripts for repetitive tasks

ANSYS Workbench Customization

Application: after analyzing separate components, customers want to quickly merge ANSYS Mechanical models to simulate the assembly

Challenge: ANSYS DesignModeler can import geometry from sub-assembly projects, but Mechanical cannot import the associated data and settings

Solution: Customization of the Workbench environment to combine data and settings from one Mechanical model with another

component models

combined model


16

Re-use of APDL Macro in WB Mechanical

Context:• Lots of ANSYS users have developed in-house models with APDL macros• How to easily integrate them into Workbench?

– Through the use of Application Customization Toolkit (ACT) based on Python and XML scripting

– Either by DIY method or Jump-start project

Example of an existing APDL macro:• Applies out-of-plane convection to a 2D turbine blade (part of an axisymmetric model)• Parameters include blade thickness, film coefficient and bulk temperature

Through the use of new “Application Customization Toolkit (ACT)” in V14.0• Expose in GUI• Define input parameters• Re-use macro


17

Convective Surface Boundary Condition in a 2D Axi-symmetric Analysis

The thickness is mandatory to create the shell elements

With ACT, add dedicated toolbar and

button for object creation

One additional convection is created as a new user defined

load

This convection enables the scope of

surfaces

Both the transformation from a

2D axi to a 3D shell formulation AND the convection itself are

generated


18

The presented solution integrates both the standard

boundary conditions and the specific

convection applied on the blade

19

Added Software Functionality

Projects that:• Enhances the value of our software to your organisation• Broadens the applicability and fidelity of the simulation• Identifies new usage methodologies• Examples:

– User-defined functions and subroutines– Custom material models– New boundary conditions– Custom physics

Porous media “wicking” model

“Hole Generator” UDF

Application: CFD analysis of gas turbine combustors

Challenge: more quickly generate the CFD mesh, including large number of small effusion (cooling) holes

• Desire to quickly change the number, location, angle for the holes to find optimal design

Solution: the Hole Generator user-defined function automatically creates and meshes any number of holes at user-specified locations

• Can also be used for cooled turbine blades

Software Tools Integration

• Projects involving the integration of multiple simulation technologies

• Extends the vision of “virtual prototyping”• An integration of multiple tools can be

used to analyze a product in its true environment

• Examples:– ANSYS Mechanical + in-house software– ANSYS FLUENT + Aspen– ANSYS CFX + 1-D software

FLUENT – Aspen Integration

• Aim was to build workflows and simple user interfaces to make CFD simulation available to non experts:• Wind Resource Assessment tools: WindModeller• Tidal Flows: TideModeller• Design of Tidal Turbines

• Use advanced numerical models and interface to industry standard tools

Tools for Renewable Energy Assessments


23

Objective• From Map to Mesh to CFD to

Report• Data Extraction and Automation

of Analysis• Built on top of ANSYS CFD

CFD solution + automated post-processing

WindModeller: Tools for Automated Solutions


24

Meshing Approach

Current recognised terrain format• .map files (WAsP format)• Generic point data file (.csv)

– X,Y,Z (DTM/DEM)

• SRTM (Shuttle Radar Topography Mission), freely available, 90m resolution (finer resolution in the US)

• OS NTF and DXF data (UK)• STL

Terrain converted to tesselated format (STL)

Meshing with custom tools• Fixed mesh structure, hexahedral mesh (5 or 9 blocks),

aimed at process automation• Template mesh morphed onto STL terrain

representation• Fast, robust, but limited for very complex terrain


25

Mesh Adaption on WT Rotor

Initial mesh1st refinement

2nd refinementFinal mesh

• Improve resolution by automatically refining mesh around the turbine location, from the specification of the rotor location and actuator disk parameters only


26

User Input

User input:• Radius and height of domain• Coordinates of the centre of the domain• Type of terrain data, type of coordinates

used.• Horizontal and vertical grid resolution
