Dsim Support

Dsim™ software is now part of the Siemens family of products. As part of this change there is an improved level of support for Dsim.

As of Monday, March 9th, 2026, the Altair Support Portal has shut down, and your cases have moved to the new Siemens Support Center. As a result, we are not able to create a support request from your email.

You should have received an email from the Siemens Support Center by Monday, March 9th, with instructions on how to set up your account. We request that you activate your account and submit your case on the Siemens Support Center, so we can address it promptly.

Here are some useful links that can help you with the transition:

We apologize or any inconvenience, and look forward to supporting you in our new portal!
