Video Tips: Workflow for Designing Electric Motors in ANSYS

A quick video showing you a great workflow for designing electric motors. It shows going from a quick template based design tool to a full 3D analysis tool

Getting to know ANSYS – Rigid Body Dynamics (RBD)

This video is an introduction to ANSYS RBD – an add on module to ANSYS Mechanical for analyzing rigid mechanisms.

Getting to know ANSYS – Icepak

As part of our “Getting to know ANSYS” video series, this video is an introduction to ANSYS Icepak – an electronics thermal analysis package in the ANSYS Product Suite.
 

“Getting to know ANSYS” Video series

The ANSYS Product Suite contains a large number of modules that are each tailored for a particular area in the simulation and analysis world.  We, at PADT, realize that many of our customers are not aware or are confused at where each of these modules fits in to the analysis spectrum. 

The “Getting to know ANSYS” videos will hopefully help everyone to understand these modules a little better.  Each video will focus on one module and will showcase the following in a mixture of presentations and mini-demos: 

  • What each module is
  • What are its capabilities
  • Why is it useful
  • Who can benefit from using it

The videos will be in the “Getting to know ANSYS” playlist on PADT’s Youtube Channel.

Please feel free to let us know how the videos are and definitely let us know which module that you are interested in and that you’d like to see next. That will help us to plan these future videos accordingly.

You can reach out to me directly at manoj.mahendran@padtinc.com for questions or followups to these or the Focus Video Tips” videos. 

Thanks!

Video Tips: Drop Impact using ANSYS AUTODYN

This is a quick video showing an example of doing an impact study using a steel slug and a reinforced concrete block.

Video Tips: Multiphysics Simulation with ANSYS Maxwell and ANSYS Mechanical – Part 2

This is Part 2 of our 2 part video series showing you a multiphysics simulation with ANSYS Maxwell and ANSYS Mechanical. In this video we take the results from ANSYS Maxwell and use it to compute the temperature distribution and finally the structural deformation due to the current through the parts.

The Part 1 video can be found here

Video Tips: Multiphysics Simulation with ANSYS Maxwell and ANSYS Mechanical – Part 1

This Part 1 of 2 video shows you the first half of a multiphysics simulation using the low-frequency electromagnetics tool ANSYS Maxwell to do an eddy current analysis. Part 2 will involve taking the results of this analysis and transferring it to perform a thermal-structural analysis using ANSYS Mechanical.

Video Tips: Parallel Part by Part Meshing in ANSYS v15.0

This video shows you a new capability in ANSYS v15.0 that allows multiple parts to be simultaneously meshed on multiple CPU cores…with no additional licenses required!

Exercising Parallel Meshing in ANSYS Mechanical R15

[The following is an email that Manoj sent the tech support staff at PADT. I thought is was perfect for a The Focus posting, so here it is – Eric]

First of all I found out a way to get Mesh Generation time (if no one knew about this).  In ANSYS Mechanical go to Tools->Options->Miscellaneous and turn “Report Performance Diagnostics in Messages” to Yes.  It will give you “Elapsed Time for Last Mesh Generation” in the Messages window.

Next I did a benchmark on the Parallel Part by Part meshing of a Helicopter Rotor Hub with 502 bodies.  The mesh settings were getting a mesh of about 560,026 elements and 1.23 million nodes.

I did Parallel Part by Part Meshing on this model with 1,2,4,6 and 8 cores and here are the results.

Can I say “I LIKE IT!”

1 core: 172 seconds (1.0)
2 core:  89 seconds (1.9)
4 core:  52 seconds (3.3)
6 core:  38 seconds (4.5)
8 core:  33 seconds (5.2)

Of course this is a small mesh so as the number of cores goes up, the benefits go down.   I will be doing some testing on some models that take a lot longer to mesh but wanted to start simple. I’ll make a video summarizing that study showing how to set up the whole process and the results.

If you are curious, Manoj is running on a PADT CUBE server. As configured it would cost around $19k. You could drop a few thousand of the price if you changed up cards or went with CPU’s that were not so leading edge.

Here are the SPECs:

CUBE HVPC w8i-KGPU
CUBE Mid-Tower Chassis – 26db quiet edition
Two XEON e5-2637 v2 (4 cores per, 3.5GHz each)
128 GB of DDR3-1600 ECC Reg RAM
NVIDIA QUADRO K5000
NVIDIA TESLA K20x
7.1 HD Audio (to really rock your webinars…)
SMC LSI 2208 RAID Card – 6Gbps
OS Drive: 2 x 256GB SSD 6gbps
Solver Array: 3 x 600GB SAS2 15k RPM 6Gbps

Video Tips: DesignXplorer – Single Objective Parameterization

This video gives an example of using DesignXplorer to automate the optimization of a tuning fork to achieve a particular desired frequency

Video Tips: Section Planes in ANSYS 14.5

A quick video showing a new way to create section planes by using coordinate systems.

Video Tips: Automatic Cross-Sections in ANSYS DesignModeler

A quick video showing how to create a script that will automatically generate standard cross-sections in DesignModeler to be used for, as an example, line bodies.

Video Tips: Automatic Contact Generation in ANSYS Mechanical

A quick video showcasing the automatic contact generation feature in ANSYS Mechanical.  This feature automatically selects the faces that are in contact or are close to contact and assigns a contact definition.
