Hello,

I am trying to install Twin Builder for HFSS and I don't see any installer for Linux package (CentOS 7). There is no readme or PDF user guide and the link for help is not working as well: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/prod_page.html?pn=Twin%20Builder&pid=TwinBuilder&lang=en&prodver=24.2

I see these files only inside the extracted directory. Any advise is greatly appreciated.

Regards,

Nader Fathy

Hi, Nader, 

Here I shared the link of Twin Builder PDF version of help. Hope that would help. 

 

You may want to file a case in the system if needed.

 

 

Best regards,

Hi Rong,

Thank you very much for helping out. I checked the documentation and find it confusing: On page 93, it says "While the majority of the Ansys Electromagnetics Suite applications and features are supported on both Windows and Linux platforms, some, including Twin Builder, are not supported on Linux. See the following topic for details: (Link doesn't open -> it points to a local windows html file)"

However, we downloaded the package "TWINBUILDERLINUXREDISTRIBUTABLES_2024R2_LINX64.tgz" but the extracted directory tree (shown in the original post) does not contain any installation script. I am not sure how to install it.

Our main purpose is to use Simplorer to run Cosimulation between Electrical and HFSS.

I am unable to file a case  because I am under an academic accounts which can't file a case in the system.

I look forward to your help and guidance.

Thanks,

Nader Fathy

Twin Builder® is only available on Windows

Additionally, v251 is not compatible with RHEL 7.x

I am confused by this answer. The package I downloaded is called "TWINBUILDERLINUXREDISTRIBUTABLES_2024R2_LINX64.tgz", meaning version 2024R2. What is v251?

Also, the name of the package implies that it works for Linux64, how come Twin Builder works for Windows only?

Finally, is there a version that is compatible with any RHEL (V7.x, V8.x, or 9.x)?

The Twin Builder Linux Redistributable Package "TWINBUILDERLINUXREDISTRIBUTABLES_202x_Rx_LINX64.tgz" contains the dependencies and scripts for running simulations with the Twin Builder Standalone solver.
This is not the Twin Builder UI that is available in the Windows version of the AEDT UI.

If you select the above the downloadable package, it provides details about the specific package.

Ansys Platform pages provide OS compatibility: https://www.ansys.com/it-solutions/platform-support
Look for the Ansys 2025 R1 - Ansys Platform Support Strategy & Plans  (PDF)

thanks
Randy
