Heavy Machinery Systems Integration using Altair Simulation products

Heavy equipment OEMs are starting to leverage advanced simulation technologies for systems design and development. This is an industry that has relied on more traditional methods, informed by decades of empirical and field test data, as well as established analytical methods. In the current and future competitive landscape, it is ever more important to shorten design lead times while better optimizing the relationship between reduced risk and an efficient, light-weight, high performance design. Altair Simulation technologies encompassed by multibody dynamics (MBD), discrete element modeling (DEM), and 0D/1D systems modeling can be a key enabler in achieving these goals. This white paper demonstrates a workflow that can be applied to a variety of problems typically faced during engineering development of heavy equipment. Available design and field data for an excavator were translated into an MBD+DEM+1D deformable body model that can predict dig forces, aid in hydraulics system development, inform downstream structural performance, and with incremental additional effort, enable fatigue, design sensitivity and optimization studies.

Re: EDEM API: Custom contact model to change particle properties

Hi,

Short version, no. There's no way around making those const values non-const, meaning there's no way to modify the Young's modulus value that is coming from EDEM.

The way around this is to make your own Young's modulus variable and replace all occurrences of EDEM's Young's modulus inside an API plugin of whatever contact model you want to use.

For example, if you are using the Hertz Mindlin, you can start from the API version of the model here:

and adjust with your own custom Young's modulus variable.

Cheers,

Re: How to set Temperature as load in Thermal Analysis?

Hi @Pouyan

Please find the modified deck.

One side of the box has 80 temperature and the other is 40.

Use SPC and card edit the spc and enter temperature value in the field D

Re: HyperMesh

Hello David,

in version 2022.2 we decided to hide the HyperMesh shortcut. Still, it remains available:

https://community.altair.com/community?id=kb_article&sysparm_article=KB0121375

As several users reported us they were struggling for getting the icon visible as it requires admin rights, we have made the icon visible again with the version 2022.3 we just released 2 days ago.

That said, is there any chance you can share the reasons why we were not able yet to convince you about the benefits of the new interface?

Best Regards,

Michael
