The ADINA CFD program
provides stateoftheart 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 LagrangianEulerian (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 NavierStokes or Euler equations.


Incompressible or fully compressible flows.


Steadystate or transient analysis.


Laminar or turbulent flows.


Flows with or without heat transfer.


Mass transfer.

Material models for
compressible flows:

Sutherland formulae for viscosity and thermal conductivity, constant heat capacity.


Temperaturedependent viscosity, heat capacity and thermal conductivity.


Pressuredependent viscosity, heat capacity and thermal conductivity.


Temperaturepressuredependent viscosity, heat capacity and thermal conductivity.


Flows with high Mach numbers.

Material models for
incompressible flows:

Constant viscosity, heat capacity and thermal conductivity.


Temperaturedependent viscosity, heat capacity and thermal conductivity.


Timedependent viscosity, heat capacity and thermal conductivity.


Turbulence models: Prandtl mixinglength model, kε model,
RNG kε model, and kω model.


NonNewtonian models.


Porous material model.
