Internal Solver Error When Solving Static Stress Simulation

david — Fri, 06 Oct 2017 14:36:00 GMT

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/Fusion-360-Nonlinear-static-stress-analysis-fails-with-Error-Internal-solver-error.html

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,
