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

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

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.
