      I am going to simulate the fluid-solid-thermal interaction by Fluent, Transient Structure and the System Coupling. Can I make the time step size a function over time in the System Coupling, because one case about the FTSI takes too much time using fixed time step size such as 0.004s.

      Hello

      Yes, you can make the time step size a function over time in the System Coupling using expressions like "0.2 if Step < 5 else 0.25". 
      Please refer to the System Coupling user guide for more information. Expressions in System Coupling (ansys.com)

      Hope this helps!
