Changing Model in middle of the simulation

  Dear,
  
  I am planning to start the simulation with K-Epsilon Realizable, and after a few hundred-time steps, I want to switch to the Reynolds Stress Quadratic Pressure-Strain Model. However, I am not sure if this is possible to be done in the middle of the simulation. Could you kindly advise if this is possible and if yes, what are the steps?
  
  thanks

  Yes, you can. Stop the model, save case & data and then change the turbulence model. Press iterate.

  Is it possible to be done with UDF, I am running the simulation on a cluster so would prefer to change it with UDF.

  Here you will require UDF and scheme not easy.
  
  Check Remote Visualization Client Help if it is an alternative for all that.

  Have a read up on Solution Steering and Journals too.
