Cloud Simulation Stuck

I am trying to run some simulations on the cloud but every time I try the simulation gets stuck at 11%. I tried to cancel and re-run but nothing happens. I am a Fusion 360 EDU user

Hi @gabriele.coppi 
The progress bar for solving is not an accurate measure of the percent completion of the analysis. The percentage is related to the step or stage of the analysis (meshing, reading the input, creating the matrices, and so on). As long as the analysis has not failed, it will still be running. The progress bar will when the analysis completes.

 

Thanks & Regards

It stayed stuck for more than 2 hours. And every time stopped at the same
time (i tried to run the simulation 13 times)

Hi @gabriele.coppi 
Could you please share the model with us?

It happens with every single model. It is not a problem related to a specific design. This simple model takes 2s on my laptop and on the cloud stays forever (I also have issue with the results, but I will open another topic for that)

Hi @gabriele.coppi 
Could you please recheck are there any need for structural constraints here? It has some warning message

Also, I am able to generate results. Could you please reduce the element size and recheck

The constraints should not be an issue (I set the remove rigid body moves, to allow for thermal expansions everywhere).

Meshing does not solve anyhting (still very low FoS with very small displacement). 

 

In every case, also if the simulation was giving meaningful results, this won't solve the issue on the fact that is not running on the cloud, but only locally

Hi @gabriele.coppi 
The educational accounts have unlimited cloud credits, but educational accounts are also limited to using a maximum of 16 cloud credits per job. Could you check to see how many cloud credits are required for your job?

 

Thanks & Regards

According to the job page, I should require 3 credits for a thermal stress simulation
