The flows may contain free surfaces and moving interfaces between fluids, and between fluids and structures. An arbitrary Langrangian-Eulerian (ALE) formulation is used

Basic assumptions used in modeling fluid flows:

 Full Navier-Strokes or Euler equations.
 Incompressible or fully compressible flows.
 Steady-state or transient analysis.
 Laminar or turbulent flows.
 Flows with or without heat transfer.
 Mass transfer.
