Enhanced Geometry
Blowers
 V6.1 includes an extended Recirculation SmartPart that allows for the definition of a linear or a non-linear fan curve between the Supply and Extract planes. In support of this change and to allow quick creation of blower geometry, we have created a new Blower Macro available in the Web Parts area of the user support area. The animation shows the results from a Microblower analysis created using the web macro.
Angled Fans
 A new option to create an angled fan primitive in a single plane has been added to the Axial Fan SmartPart.
If required the hub and cowl geometry can also be added using either FLO/MCAD or the new Angled Fan Macro available in the Web Parts area of the user support area. The animation shows an axial fan mounted at 45 o in the corner of an idealized PC system design.
Tet & Inverted-Tet Primitives
The Geometry Palettes in the Project Manager and Drawing Board have been updated to include 2 new primitives: Tet and Inverted Tet.
These objects can be used to create more accurate thick geometry such as spheres or chamfers. The sequence below shows a single Inverted Tet, with 3 abutting Tets on the aligned triangular faces and then used to complete part of a facetted sphere.
 
The sloping faces of these new primitives utilize the cut-cell and porosity treatment equivalent to prisms and can be used for applications requiring full conjugate heat transfer.
Core Product Synergy
Separate EM & Thermal grids
The grid in v6.1 is now stored independently for FLO/EMC and FLOTHERM within a single project definition. This reduces the time required for integrated simulation by allowing engineers to operate with appropriate meshes to capture the differing physics in the two analyses, one optimized for thermal simulation and one for EMC simulation.
The Project Manager has an icon enabled to link directly to the parts website, www.smartparts3d.com. The link operates as follows:
- Browse the site and click on the Save icon for the part required – for example, Delta Fan – part no. FFB1224EHE:
- The selected part will automatically appear as a child object of the selected assembly.
Thermal Solver Speed/Efficiency
64-bit support
FLOTHERM is now available on Windows for 64-bit Extended Systems (X64) including AMD Athlon 62, AMD Opteron, Intel Xeon with EM64T and Intel Pentium with EM64T as well as Solaris 8, 9 & 10 on SPARC platforms.
Post-Processing
Annotation – Cursor Values
Field plots in FLOMOTION can now be annotated with field values and location via the Cursor Values dialog with a left mouse button click. If the image is then rotated or zoomed or the plane is re-located, the annotations will automatically update to reflect the new orientation, viewpoint or plane location.
Particles - Adaptive Time Steps
This is an update to the algorithm used to create particles in FLOMOTION that automatically calculates on a local basis the appropriate Integral Time Steps for the tracks. The primary benefits of the new approach are that the tracks will be more accurate, faster to create and dynamic when sources are re-located. It is also now possible to interrupt a particle plot being created by clicking on <ctrl>c at any time. |
