  Hi everyone,
  
  I am trying to set up a DUALCESE model to simulate a gas jet but I am getting a hierchy error. From what I have learned I need to define all my DUALCESE keywords under the DUALCESE_MODEL hierchy but the DUALCESE_MODEL keyword seems to dissappear from the keyword deck after I save the project.
  
  Can someone please guide me on ho to set-up a correct hierchy for the problem or if there are any documents availabe, would really appreaciate it. Thanks in advance.

  Hello Kumar,
  
  How are you setting up this model? Is it LS-PrePost? If so, what version of LS-PrePost is it?

  HI Nanda,
  
  Thanks for your response. Yes, I am using LS Prepost R-13 (v4.12.3) for the set-up.
