APDL Scripting in Ansys Mechanical

Overview

Training eLearning Expert

Learn how to increase the functionality of Ansys Mechanical with APDL command objects for special tasks. This training is offered as a 3-day course or alternatively as a self-paced eLearning course.

Duration
3 days

Prerequisites
Basic knowledge of Ansys Mechanical

Software used
Ansys Mechanical

Benefits
  • Access to functions beyond the Workbench GUI
  • Understanding APDL scripts and working with them independently
  • Impact of what Workbench imparts to solvers using APDL
  • Creating own APDL macros

Description

Ansys Mechanical is a powerful tool that offers engineers a wide range of functions and a largely automatic selection of efficient and proven model settings. With APDL command objects (Ansys Parametric Design Language), you can extend your Ansys Mechanical setup to realize your own ideas of model design. You can define complex boundary conditions and perform evaluations exactly as you like.

In this training, you will gain a deeper insight into the interaction between Ansys Mechanical and the Mechanical APDL Solver (MAPDL). This allows you to examine and modify the model structure generated by Mechanical. You will also learn how to use APDL as a programming language, for example to implement automated evaluations.

We will use examples from the field of structural mechanics, but the methods are independent of this and can be transferred to other physical domains. This training is suitable for users who already have a command of the basic functionalities of Ansys Mechanical and want to gain access to all the possibilities of the MAPDL solver. Take this opportunity to expand your skills!

Over the past few years, I've been looking for sources to learn APDL. Of course, the first source I searched was the Internet, and I also read through books. However, I must say without a doubt that your eLearning is the best I have ever come across on the subject of APDL. This is the first time I have seen and understood so many things in APDL in such a clear and concise way.

Do you have questions on the training or the eLearning?

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). 

Can I test the eLearning offer without obligation?

To get a clear impression of our online learning format, we offer you a trial allowing you access to the starting module of an eLearning course of your choice. No costs, no cancellation period or anything similar. Moreover, with this free test access you can check all the technical requirements for a smooth learning process. You can easily request the free module from any eLearning course.

How much time should I allow for an eLearning course?

Each online course day comprises four eLearning modules. You should ideally allow 90 to 120 minutes of uninterrupted learning time for each module. This will allow you to acquire the knowledge provided by a module and to consolidate it through quiz questions and Ansys exercises. By dividing each module into micro learning units, you can also make good use of smaller time windows, such as on your commute.

For how long can I access the learning content?

Prerequisite for the use of the eLearning courses is the use of a personalized access to the CADFEM learning platform. When purchasing an eLearning course, access to the learning platform is 365 days. As a subscription user, access to the learning platform starts and ends with the start and end of the flat rate. With the start of a further learning product (Learning Subscription, training, eLearning), access to your content is extended by 365 days.
