What's new in PHOENICS

PHOENICS has been updated for its 2009 release. Updated features include:

Changes to the Earth Solver

MOFOR has been enabled in parallel PHOENICS.
CVD has been enabled in parallel PHOENICS.
To reference the value of a variable at a specific location, the physical co-ordinates can be enclosed in {}, for example the temperature at (3.2,5.8,2.5) is TEM1{3.2&5.8&2.5). Previously only cell locations could be given as TEM1[3&8&5].
A better initial guess at the size of the F array required for the case has been provided. If a further expansion fails due to lack of memory, a scratch file is used for temporary storage. This allows bigger cases to run on 32-bit systems without adjustment of CHAM.INI.
The use of material >= 299 for blockage causes cut cells to be treated as blocked and opens un-cut cells. The image shows the detection of a variety of curved surfaces.

Changes to VR Editor

Objects can be tagged to extend to the domain end. They can also be tagged to always lie at the domain end. This makes changing the domain size easier as tagged objects will follow automatically.
For the WIND_PROFILE object, the profile starts in the first un-blocked cell in each column. Previously it always started at the lower boundary of the object. This makes it easier to introduce wind profiles over terrain objects.
In FLAIR, the fire and smoke dialogs have been updated to use current standards terminology. The Smoke Settings dialog now refers to Heat of Combustion, Particulate smoke yield and Mass specific extinction coefficient. These values can be found in references such as the CIBSE Guide E.
In FLAIR diffuser objects can be rotated about any axes. Previously they had to align with the grid.
The InForm Editor (now renamed Save Block Editor) and other TCL-based utilities such as Facetfix are now supplied as executables, so there is no need to install TCL.
Fully rotational clipping planes have been introduced into the Editior and Viewer

Changes to VR Viewer

The handling of PHOTON-style PLINE elements has been added.
Images can be saved as jpg files, in addition to the previous options of gif, bmp and pcx.
Option has been added to display the results in a selection of non-SI units
