Transient Structural: Is there anything I must consider in order to select a time step?

  I'm thinking in terms of the Courant number that relates the mesh size with the time step.
  I'm also wondering if there are internal mechanisms in Ansys that should be taken into consideration for the operator (me) to select a time step.
  I don't know if this would be relevant, bot I'm studying an Fluid-Solid iIteraction (FSI) between an aircraft wing and air, and the meshing varies depending on the part of the wing.
  Thank you in advance!
