I'm using Simulation 360 pro.
So now and then I get this message when running analysis on the cloud:
"Use SSAP0G or SSAP0GC for models containing gap or contact elements"
When I try to run the same project later, it may run correctly, without error.
So it is not a problem with the project. Is this a capacity problem with the cloud servers?
This issue seems like it may be model dependent and I recommend to create an archive of the model and open a support case from within the Autodesk Subscription Center.

I do not think it is model dependent. When I run the same model some time later, it may succeed.
It happens with all kind of projects. Simple simulations and complex simulations.
