"Capping" refers to the number of "Jobs" that you can run with your account.
Each analysis type, for example, Fill, or Warp, or Cool, or Fill+Pack, is considered to be a single Job. Thus an analysis sequence such as Fill+Cool, is valued at two (2) Jobs. Likewise, Cool,+Fill+Pack,+Warp is valued at three (3) "Jobs", since Fill+Pack is a single Job. You can top up your Autodesk Account to ensure that you have sufficient Jobs to complete your analysis sequence.
If you have insufficient Jobs left in your account, and you send an analysis to the Cloud, the analysis will fail and you will receive an error message.
For example, if you send an analysis sequence such as Cool+Fill+Pack+Warp to the Cloud, with only two (2) Jobs left in your account, the first two analyses will run successfully and the third (Warp) will fail with a message similar to the one below.
