CFD software adds more modelling options
The latest Flow-3D offers users an advanced new VOF technique, extensions to the powerful general moving objects model introduced last year and numerous other enhancements to users' modelling options.
Flow Science has released a new version of its Flow-3D computational fluid dynamics software Version 9.1 of Flow-3D offers users an advanced new VOF technique, extensions to the powerful general moving objects model introduced last year and numerous other enhancements to users' modelling options
In addition, Version 9.1 will support 64bit Windows and Linux RedHat Enterprise 3.0 for the x86 64bit processors in AMD Opteron and Intel Xeon workstations.
The following is a summary of the key benefits to be found in Version 9.1.
New models include: a split Lagrangian VOF advection model for tracking sharp and diffuse fluid interfaces even more accurately; an extended "leaky dielectric" model, which works in conjunction with Flow-3D's electric potential, electric charge and dielectric models; a new cavitation potential model designed to predict die erosion due to cavitation during filling in high pressure die casting; And a new two-fluid interface slip model.
In other improvements, the general moving objects model has been extended to enable moving components to have the same heat transfer and mass source capabilities as nonmoving components.
Additional extensions allow for moving history probes and noninertial forces on moving components and the ability to model particles adhering to moving objects.
The air entrainment model has been modified to allow for its use without requirement of initiating any turbulence model and to model bulking and the escape of air back into the atmosphere.
Two new capabilities have been added to the two-fluid (liquid and compressible gas) evaporation/condensation model: to allow condensation in pure gas and evaporation in pure liquid for both sharp and diffuse interface cases; and to allow for preferential vapour nucleation (boiling) at solid walls.
The accuracy of free surface curvature evaluation has been improved by including more fluid cells in the calculation.
Additional improvements in free surface normal evaluation result in reduced noise in surface tension pressure.
These enhancements, combined with the new split Lagrangian VOF method, improve the accuracy of the surface tension model in general.
The Flow-3D graphical user interface has been improved to allow for more complete setup via the interface, rather than text input, and to add numerous other user conveniences.
In addition, the visualisation suite has been enhanced significantly with streamlines and vectors for 3D plots, the ability to view mesh and geometry file overlays and additional output options.
Flow Science has also made several additions to supported platforms for this new release.
Version 9.1 will support 64bit Windows and RedHat Enterprise 3.0 for the x86 64bit processors in AMD Opteron and Intel Xeon workstations.
In addition, Version 9.1 will also support Windows XP Pro IA64 and Windows Server 2003 IA64 for the Intel Itanium 2 workstation.
Moreover, for the first time, Flow-3D will also be able to be run in shared-memory parallel mode on 32bit Linux and 64bit processors running both Windows and Linux.
Flow Science has commenced shipment of the new release to customers under maintenance contracts.
