I have been working on this file in the same version of Autodesk Simulation, but when I closed it and try to open it after an hour or so, the error popped up and won't able to open the file.
I have attached the screenshot of this error. Well, it reads as follows: "The requested model was not loaded since it contains features that this version does not support. Please conatct your Autodesk Simulation service team."
However, we have only 2013 version in the office and I created this file in 2013 version. Looks like error itself is an error.
Do any of us have this problem? Is there anyway to resolve this error and make the file working?
