  Severity: Informational
  
  Introduction: CATIA and SolidWorks do not allow multiple instances to be run at once. Data
  collisions may occur if a user or non-ModelCenter process interacts with CATIA while ModelCenter is
  attempting to access CATIA. Data collisions may occur if a user or non-ModelCenter process interacts
  with SolidWorks while ModelCenter is attempting to access SolidWorks.
  
  Issue: CATIA or SolidWorks may experience data collisions if a user or non-ModelCenter process
  interacts with either product while ModelCenter is accessing the same program. ModelCenter 12.0
  and newer provide a locking mechanism to serialize ModelCenter’s interactions with CATIA and
  SolidWorks to prevent data collisions. However, it is possible that a user or non-ModelCenter process
  could interact with either CATIA or SolidWorks while the same program is being accessed by
  ModelCenter and result in data collisions. For example, launching CATIA or SolidWorks from the Start
  menu while ModelCenter is using the same program could invalidate results without the user’s
  knowledge.
  
  Impact: Data collisions may occur if a user or non-ModelCenter process interacts with CATIA while
  ModelCenter is attempting to access CATIA. Data collisions may occur if a user or non-ModelCenter
  process interacts with SolidWorks while ModelCenter is attempting to access SolidWorks. Data
  collisions of this nature could produce incorrect results without the user’s knowledge.
  
  Resolution: While running a trade study or a workflow that utilizes CATIA or SolidWorks, do not
  interact with the same program outside of ModelCenter.
