Fusion 360 Simulation Stuck

[agepfert067]

Trying to run a simulation on Fusion 360 but it remains stuck at 1% (5% in the "Solving" when you break it down). I have updated Fusion 360, tried it online, tried it on multiple computers, and tried to save the file as a new file name and re-solve. My internet has been stable while I have been running the simulations.

Hi @agepfert067,
Could you attach the diagnostic log file?

1. Restart Fusion
2. Open the design and send a solve for the study
3. Go to the Help pull-down > Support and Diagnostics > Diagnostic Log Files

The log file might indicate the problem causing the solve to be stuck.
Also, I'm curious if this is happening with a particular design, or does a solve get stuck for any simulation?

Best regards,

It is happening with one specific design but I am only trying to run one specific simulation. The design has very complex geometry but I am unable to simplify the design or mesh. I mentioned earlier that it stalls at 5% but occasionally it will "fail" in the receiving stage of the simulation but I am not able to see what fails.

Thanks for providing the log files. The document name is called "Femur" and I'm guessing that the model is a 3D scan of bone that has a very high number of face facets from a mesh body? If so, it is recommended to convert the mesh body to a TSpline to greatly reduce the number of faces before using it in simulation.

[agepfert067]

Yes that is correct. Does converting to the TSpline alter the geometry of the design?

[henderh]

In theory it shouldn't alter the geometry significantly, although I'm not familiar enough with TSpline conversions to be 100% certain this is true in every case.
You could insert the mesh body superimposed on the TSpline body for a visual check.
