You can create a new simulation process by importing a 3D XML file. 
      
    
      Before you begin: You can import a simulation process only to the same release of Optimization
                    Process Composer from which it was exported.
- 
          
            From the top bar, click .
        
- From the Import 3DXML dialog box that appears, select the Path and the  Name of the file to import.
- From the Import Options, select Import as New  to  create a simulation process that is a local copy of the original. You become the owner of the new simulation process, and new internal identifiers, business
            rules, and lifecycles are applied to the new process. There is no connection between the
            new simulation process and the 3D XML file; changes to the 3D XML file will not be
            propagated to the new process.  
- 
          
            Enter a Duplication String that Optimization
                    Process Composer uses to name the new simulation process. (Optimization
                    Process Composer prepends the original name of the process with the text string  that you enter.)
          
          
        
- Click OK.The imported simulation process appears in Simulation Finder in an Explore window. 
- From the Explore window,   select  from the context menu to open the simulation process. You cannot open the process from the action bar.
