Advanced Applications of Fluid Dynamics and

Structural Mechanics Simulation in the Upstream

Oil and Gas Industry

Introduction

© 2010 ANSYS, Inc. All rights reserved. 2 ANSYS, Inc. Proprietary

• The marketing for the seminar announced

– Computational Fluid Dynamics (CFD) and Computational

Structural Mechanics (CSM) are extremely powerful tools

to provide information and insight to engineers and

scientists involved in the upstream oil and gas industry.

– This seminar will feature an introduction to the use of the

ANSYS simulation tools in the industry followed by

technical presentations from ANSYS UK and industry -

speakers in the two themes of produced fluid and safety.

• Let’s look at the agenda
