The ADINA CFD (Computational Fluid Dynamics) program provides state-of-the-art control volume and finite element capabilities for incompressible and compressible flows. The flows can contain free surfaces and moving interfaces between fluids, and between fluids and structures. An arbitrary Langrangian-Eulerian (ALE) formulation is used.
The procedure used in ADINA CFD is based on finite volume and finite element discretization schemes, with a most general and efficient solution approach. General flow conditions in completely arbitrary geometries can be solved. |
