ANSYS Motion - a New Dedicated Multibody Dynamics Tool

Our clients working in multibody dynamics and kinematics have an outstanding new simulation tool: ANSYS Motion.

ANSYS Motion can help engineers…

  • Find more accurate boundary conditions during static analyses
  • Solve big deformation problems while incorporating non-linear material properties
  • Perform kinematic analyses of mechanical systems
  • Analyze high-speed rotation problems with complex geometry

Tightly coupled rigid and flexible solvers that are powerful and fast allow engineers to study situations beyond what is possible in ANSYS RBD (Rigid Body Dynamics). Modal flexible, meshed flexible, and rigid parts can be tied together with standard joints and connections so accurate loadings on the components can be calculated.

This standalone solution for multibody dynamics and flexible multibody dynamics uses its own pre- and post-processor and solver. Pre-processing is integrated into ANSYS Mechanical via an ACT extension.

Maximizing Memory Performance for ANSYS Simulations

Memory, or RAM, is important when you’re configuring computers for high-performance computing (HPC). Computer performance is affected not only by the amount of RAM but also by the amount of bandwidth, or transfer speed, between the processor and the memory. The bandwidth is affected by the speed of the memory stick, but the way memory sticks are configured on the motherboard is even more important.

CPUs can access information on multiple memory sticks in parallel through use of memory channels. Modern CPUs can access between 1 and 8 memory channels simultaneously (model specific). Not only does this capability affect the machines performance, but we have found that many computers are not configured to make use of all their memory channels, which hampers performance.

Modeling Bolted Connections

Modeling Bolted ConnectionsMany methods are available to model bolts. What are the best ways ANSYS simulation software can help engineers with bolt simulation, and how might an engineer approach bolt projects?

In this recorded webinar, Tyler Coffey, SimuTech FEA Consulting Engineer, shares his expertise using ANSYS Workbench™ in models that…
  • Use bonded contact to attach the parts (bolts not included)
  • Use beam elements to model the bolts
  • Use solid elements to model the bolts but do not model the threads
  • Include the threads in modeling

FEA Best Practices Video Series

New to FEA or simulation tools in general? Our training videos can help.

This eight-video course is geared toward engineers and engineering managers. While the course includes information on ANSYS FEA, this series is also a good primer for understanding FEA as an important tool for accurate design, whichever commercial code you’re using (ABAQUS, NASTRAN).

We’ll discuss element theory, element types, preprocessing, solution, and postprocessing, and much more. Watch the introductory video (see below) at no charge for more details on what’s covered.

All of the videos in this course may be viewed in SimuTrain, our subscription-based portal. SimuTrain provides 24/7 access to lots of ANSYS-related training materials like this FEA series, plus more “best practice” videos, our popular Quick Start videos, and much more.

Interested? Request a free trial or contact your local SimuTech office.
