  hello In fluent, for the transient table in a transient boundary condition of a wall temperature , should the time step be the same for example 0.01 or i can have 2 different time steps for the first three values of temperature for example 0.01 and for the other values 1 second ?
  thank you

  Hello,
  
  You can independently define your time step size and it's variation with respect to time with the help of an expression. If your time step size is a function of time (actual time), you can simply write an expression as a function of time. If not, you can use 'If' function while writing an expression.
