Optimization of Flow Geometry Using Fluent Adjoint Solver

Minimum pressure loss, maximum efficiency, and homogeneous flow fields

Overview

Training Advanced

In this course, you will learn how to effectively apply tools available in Ansys CFD for shape optimization of your flow geometry. This training is offered as a 2-day course.

Duration
2 days

Prerequisites
Basic knowledge of Ansys Fluent

Software used
Ansys CFD

Benefits
  • Perform shape optimizations with the Fluent Adjoint Solver
  • Select robust solver settings and an appropriate mesh-morphing method
  • Simple implementation of automated flow optimization
  • Practical exercises for different types of CFD tasks

Description

Whether in systems and process engineering, automotive development, or the aerospace industry, the optimization of basic external or internal flow geometry designs leads to energy savings and improved processes. Typical tasks that lend themselves to optimization are minimization of pressure loss in a flow, homogenization of a flow field, maximization of an efficiency or a heat transfer. In this course, you will learn – taking installation space limitations and other restrictions into account – how to optimize your design according to one or more objectives based on an existing flow simulation with the Adjoint Solver. You will also learn how to use the Adjoint Solver independently of automated shape optimization in order to gain important insights into the complex nature of flow phenomena.

You will learn how the solver works and how to define target quantities and restrictions. Additionally, you will receive numerous tips for robust solver settings and for selecting a suitable mesh-morphing method. You will apply your acquired knowledge in practical exercises on various types of CFD tasks. You will also learn how to use the solver independently of automatic optimization by showing sensitivities of the input quantities with respect to the target quantities. This course is designed for experienced Ansys Fluent users.

Do you have questions on the training?

When will I receive the final confirmation for my training booking?

Straight after you sign up, an automatic confirmation of receipt will be sent to the email addresses you provided. Once you have successfully verified the data you provided, you will receive your personalized sign-up confirmation, containing further information on course fees, the billing address, etc., by email within two to three working days.  

As soon as the minimum number of attendees has been reached, you will receive a final training confirmation containing further information. If you have booked an on-site training, we recommend that you wait until you have received this final confirmation before booking your travel and accommodation.

If the minimum number of attendees is not reached, we reserve the right to cancel the training seven days before it is due to start at the latest. We are happy to inform you on changing your booking to an alternative date. Please note that we accept no liability for hotel or travel bookings that attendees have already made.

When is the sign-up deadline for a training?

Training places will generally be allocated based on the order in which attendees sign up. For this reason, we always recommend booking for your desired date as early as possible.

As long as a coures still has free places, it can be booked.

At what time do the training courses begin and end?

Usually the training courses start at 9:00 am and end at 5:00 pm of the respective local time. The actual course times will be stated in the booking confirmation. Please note that, depending on the training host, there may be a possible time shift between your and the provider's local time. Therefore all local times are provided with the valid time shift to Greenwich Mean Time (GMT). 

What are the methods used?

Course, demonstration and practice on the software. Training materials are in English language.

What are the evaluation methods during this training?

The training includes intermediate and final exercises to practice the elements covered in the training. The trainer will present the resolution of these exercises and will check the good understanding of each module of the course with the help of MCQ. A training certificate will attest to the validation of the knowledge assessment for each module and for the overall training.
