What is CFD?

CFD gives you velocities, pressures, temperatures in flowing liquids and

gases (including temperatures in surrounding solid structures)

Typical applications include:

Reducing pressure drop

Predicting aerodynamic lift/drag

Ensuring adequate cooling

How do fluids influence a structural

analysis?

Temperatures will induce stresses and deformations

Pressure variation might affect the shape of a structure


9/20 2011 ANSYS, Inc. May 20, 20129

What is Electromagnetics?

Emag analysis is about understanding low or high frequency

electromagnetics fields.

Typical applications include:Electrical machines, transformers

Actuators, sensors

Circuit boards

Antennas, High speed channels

Electromagnetics interference

How do electromagnetic fields influence a

structural analysis?

Magnetics forces will induce stresses and deformations

High frequency heat losses will induce temperature variations

Motivation

Exchange files are

frequently used to

transfer quantities from

one simulation to

another.

Efficient mapping ofpoint cloud data is

required to account for

misalignment, nonmatching units or scaling

issues.

Mapping Diagnostics

Option to create nodal based named selections for mappednodes, unmapped nodes, and outside nodes.

Can help the user better understand the

mapping.

Importing Multiple Files

Multiple files can be

imported for

transient analyses or

to handle different

data to be mapped

on multiple bodies
