Hi

This describes the difference between the two and when to consider one or the other:

To add since for FSI (2-way) , then Implicit will be used (Fluent – > Transient Structural via system coupling say), so that will determine that it is implicit (Transient and static struc. systems are Implicit only)

There is also ICFD in Ansys LS-Dyna coupled to structural LS-DYna/Implicit solver –

All the best
