Fluids present two major challenges for the standard Finite Element Method:

Knowing which software uses which method is half the battle. Fluids present two major challenges for the standard

The fluid equations and solid equations are solved sequentially using separate solvers. Data is transferred across the shared boundary interface at every timestep. fea fluid dynamics

To understand FEA in fluids, you must first understand why the methods are usually separated.
