Faster, further, quieter – learn how to efficiently simulate complex motion sequences.

When it comes to developing or improving complex systems, e.g., crankshafts, transmissions, or even entire power trains, questions relating to how well the system functions, the resulting loads, and derived properties such as smoothness or durability are often of great interest. ...

When it comes to developing or improving complex systems, e.g., crankshafts, transmissions, or even entire power trains, questions relating to how well the system functions, the resulting loads, and derived properties such as smoothness or durability are often of great interest. Transient processes like these are typically examined via multibody simulation (MBS, also multi-body dynamics, MBD). Ansys Motion provides the user with a high-end solution. This course has been specifically shaped to provide the kind of introduction to the program that will enable you to use the software in an efficient manner. Through the use of many practical examples, you will become familiar with the interface so you will soon be able to configure the right settings yourself.

Ansys Motion comes with its own preprocessor and postprocessor. The newly developed Workbench interface now provides the user with a powerful postprocessor in addition to the solver. During the course, the entire model setup and simulation will be performed in Workbench. Post-processing is carried out in Motion's own post-processor.

This course is aimed at simulation engineers involved in the development of complex, moving structures. It does not matter whether you already have experience in the field of multibody simulation or in simulation with Ansys or if you are a complete beginner. This course offers the perfect introduction to Ansys Motion and shows you the best ways to use it.

You will be enabled to build, solve and correctly interpret MBS models for the simulation of complex motion sequences. You will thereby leave behind the basic assumption that all bodies are rigid   and learn how to consider flexible and therefore oscillating bodies. This will enable you to calculate bearing loads and requisite drive torques in the shortest possible time and also to uncover design deficits and kinematic constraints.

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 seminar fees, the billing address, hotel recommendations, 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 on how to get to the venue. 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 help you change 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 seminar still has free places, it can be booked.

When 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). 

The following time difference to GMT during summer/winter time applies to the individual training providers:
