Internal Solver Error When Solving Static Stress Simulation

[david]

I have what I'd like to think is a simple model. I first ran a Shape Optimization and now I want to validate my changes with a Static Stress simulation. My Pre-Check is clear. When I solve using the cloud, I eventually receive an Error: Internal Solver Error with no explanation. How can I debug this? I also included a screenshot from trying to run this locally.

Hi @david, 

I'm sorry to hear that. It rarely happens when you receive the results from A360 server. 

I tried to run your file and it was succeed. 

Have you seen this article? 

Fusion 360 internal solver error : https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/Fus...

Please try the workaround if you can't resolve it, please let me know. 
I'm sharing the file succeed with running so please find it. 

Many thanks, 

Ahreum.

I exported a f3d and re-uploaded it. I still cannot run the analysis.

Hi @david, 

I'm sorry about it. It turned out that is a known issue regarding bolt connector. the development team are working on int. (ARRO-8808) 

As a workaround, I found this thread. could you try this?

Sorry for the inconvenience caused. If I receive any response, I will get back to you 

Many thanks,
