Hello mr. assistance. Im the newone in Altair Inspire (v2023). I don't know how to fix this problem. Can you help me to fix this ?
When analyzing the part after optimization, the process suddenly shuts down and pops up a notice that announces" Analysis Error 1479." I tried to delete some geometries and forces that I suspected were causing this problem, and then tried again, but it did not work.
Thank you.

Hi @Hung_25,

This looks to be an error code reported by OptiStruct, based on these other Discussion posts:

https://community.altair.com/discussion/18046/error-in-optistruct-analysis

https://community.altair.com/discussion/20608/error-1479-in-the-input-data

Since the same solver is being used, the outcome may be similar for Inspire. The outcome of both Discussions is that there is a formatting error in the input file, mostly related to polybeams. Does your model feature any of those elements?

Can you share the model?

Have you tried using the most recent version (2025.0)?

Hope this helps!
