Hello Team,

I have been testing LS-DYNA license features at the request of a customer.

I obtained a license file from the Ansys Licensing Portal in March of this year.

As far as I know, the standard Ansys LS-DYNA license includes the features "advanced_meshing" and "dyna". For parallel processing, an Ansys LS-DYNA HPC license with the "dysmp" feature is required.

Therefore, when running an LS-DYNA model with a single core in Workbench or LS-Run, only one "dyna" feature is used. When running with multiple cores, one "dyna" feature and multiple "dysmp" features are used.

However, when I run a model using the license that was issued in March, I see a new feature called "dyna_solver_core" being consumed up to the number of available features. Once the number of requested cores exceeds the available "dyna_solver_core" features, the job then consumes one "dyna" and multiple "dysmp" instead of "dyna_solver_core".

I searched for "dyna_solver_core" in the attached Product to Feature Map.pdf (the latest version available in the Download Center), but I could not find any reference to this feature. It appears to be similar to the licensing model used with legacy LSTC LS-DYNA licenses. Has this feature been incorporated into the current Ansys licensing scheme?

If anyone is familiar with this feature and can provide additional information, I would greatly appreciate your insights

Hello,

Here's the latest update from our product manager:

"The dyna_solver_core increment is not yet productized and therefor in the license file - if I am not mistaken - has a "beta" in its name. It's available on request for selected customer. As per the Recent Development slides from last years LS-DYNA User Conference - we're working on a migration towards FlexLM and the next step will be the creation of a product - then we will update you all further. (And then you should find it correctly in the product-to-feature-map file 🙂 )

The executable checks for the dyna_solver_core first, and then goes with dyna+dysmp. "

Regards,

Nanda
