The ADINA CFD program provides state-of-the-art finite element and control volume capabilities for incompressible and compressible flows. The flows may contain free surfaces and moving interfaces between fluids, and between fluids and structures. An arbitrary Lagrangian-Eulerian (ALE) formulation is used.

The procedure used in ADINA CFD is based on finite element and finite volume discretization schemes, with a most general and efficient solution approach. General flow conditions in arbitrary geometries can be solved.

Basic assumptions used in modeling fluid flows: Full Navier-Stokes 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.
