PyroSim 2018.1.0329

What's New

This version of PyroSim is designed for FDS version 6.6.0. It uses version 1.8.0_162 of the Java VM.

Changes since PyroSim 2017.2.1115:

• Added support for the WIND namelist.
• Added hardware shaders to render scene geometry for improved performance and quality.
• The default smoke detector model has been changed from ionizing to photoelectric.
• Improved how FDS mesh outlines are written to the PyroSim Results geometry file by no longer showing outlines for non-corner edges.
• Species are now shown in the tree view.
• For Layered surface Ignite At temperature, improved clarity and added validation.
• PyroSim now includes four generic spray models based on reasonable defaults.
• Results preview now uses a start time of zero even if the simulation start time has been entered as a negative number – preventing unnecessary FDS simulation time.
• Changed the default value of REAC namelist parameter CRITICAL_FLAME_TEMPERATURE from 1327 C to 1427 C.
• PyroSim now uses negative volume flow specification rather than the REVERSE flag to specify flow direction in HVAC ducts.
• Fixed a bug in the FDS Run Dialog that caused the hours field to get stuck at 596.
• Fixed a bug in the names of imported CAD objects that could cause some non-English characters to be displayed incorrectly.
• Fixed a bug that prevented objects from showing changes to appearance settings.
• Fixed a bug that could cause a crash when running FDS.
• Fixed a bug importing FDS files with a gravity ramp that prevented the GVEC multiplier from being applied to ramp values.

Changes to Results:

• Objects in the Pyrosim geometry file now appear and disappear based on FDS control logic.
• Added hardware shaders to render scene geometry for improved performance and quality.
• Improved shading of occupants. Clothes look “cleaner” and occupants brighter.
• Hardware accelerated occupant display now works on Intel GPUs for improved performance.
• Hardware accelerated occupant display is now available for newer AMD drivers – previously some updated AMD drivers required software rendering.
• Improved object outline visibility when using transparency.
• Boundary quantities are no longer shown over OPEN vents.
• Mesh outline visibility is now enabled by default.
• Slice vectors thickness can now be increased to support high resolution screenshots.
• Fixed a bug that could cause a crash when there was only one isosurface.
• Fixed bugs that could cause missing display of boundary quantities when using multiple meshes.
• Fixed a bug that could cause a crash if manually hidden obstructions were activated via control logic.
• Fixed a bug that could cause errors when opening FDS results if the SMV file contains certain non-ASCII characters.
• Fixed a bug where a boundary quantity for an activated obstruction might show at the wrong time.
