Commercial FE and CFD codes used by MEFOS PDF Print E-mail

Beside software developed by MEFOS commercial FE codes are also used.

FLUENT®

FLUENT® is a general-purpose commercial computer program for modelling fluid flow, heat transfer, mass transfer and chemical reactions. FLUENT® solves the full steady-state and transient Navier-Stokes equations using a finite volume method in 2-D or 3-D geometries.

FLUENT® allows the user to model a wide range of fluid flow processes including laminar or turbulent flows, incompressible flows, heat transfer and reacting flows. In reheating-furnace applications, FLUENT® is used for analysis of the gas flow distribution, convective and radiant heat transfer, etc. It gives a greater knowledge of the flow fields and plays an important part in the design process. It is also possible to incorporate one's own models into FLUENT® through user-defined C subroutines such as predictions of NOx concentration, etc.

FLUENT® is available on a wide range of hardware platforms from PCs to supercomputers.

 

PHOENICS

PHENICS is a general purpose software for modelling fluid flow, heat transfer, mass transfer and other transport phenomena. PHOENICS solves the full Navier-Stokes equations both stedy-stage and transient for 2-D and 3-D geometries.

It is possible to incorporate custom-made models in PHOENICS through user-defined FORTRAN sub-routines.

PHOENICS is available on a wide range of platforms such as PC, Linux etc.


SYSWELD®

A commercial computer program used to analyse surface treatment, welding and quenching. The computer code, SYSWELD®, uses FEM for the modelling of manufacturing processes involving metallurgical phase changes. SYSWELD® includes:

  • classical capabilities in the field of nonlinear analysis such as heat transfer and mechanics.
  • additional capabilities to take interactions between metallurgy and both heat transfer and strain-stress computations into account.
  • fully coupled heat transfer and metallurgy analysis (metallurgical phase computation, modelling of latent heat effects due to metallurgical transformations using an enthalpy approach and thermophysical properties depending on metallurgical phases).
  • stress-strain computation (thermal and metallurgical loading, phase transformations lead to volume variations and special material behaviour at different metallurgical phases and transformation plasticity).

LS-DYNA3D

LS-DYNA3D is an explicit three-dimensional finite element code with parallel computing capacities for analysing the large deformation dynamic response of inelastic solids and structures. A contact-impact algorithm permits gaps and sliding along material interfaces with friction. Using a specialisation of this algorithm, such interfaces can be rigidly tied to admit variable zoning without the need for transition regions. Spatial discretisation is achieved by the use of 8-node solid elements, 2-node beam elements, 4-node shell elements, 8-node solid shell elements, truss elements, membrane elements, discrete elements and rigid bodies. The equations of motion are integrated in time by the central difference method. LS-DYNA3D currently contains more than fifty material models and eleven equations of state to cover a wide range of material behaviour.

MARC

MARC is a commercial nonlinear FEM program with an implicit solver and Parallel processing capabilities. MARC is especially used for analysing forming processes such as forging, rolling, extrusion, etc. Using MARC, modelling and remeshing in 3D can be done with tetrahedral elements. Remeshing is done automatically by the program at certain degrees of strains. MARC supports thermomechanical coupling, and therefore analysis of long cooling times can be combined with analyses of transient processes.
