PyroSim 2007.1 RC2

What's New

We are working on PyroSim 2007.1 RC2. It should be published in the next few days.

Upcoming Features in RC2:

• [Bug Fix] Objects intended to be deactivated by time devices never go away if the object is latched.
• [Documentation] Tutorial to measure heat flux and layer height.

2007.1.0830 RC1 Bugs Fixed in this Release:

• Particle sampling factor would not write if set to 1 (not the default value).
• SURF lines containing only SLIP_FACTOR would lose this property.
• Crash when removing a component of a layer zoning device that was in use by another object.
• Crash when loading PSM files that contained images generated from DXF files. Found by Brian Melly, Triad Fire.
• Hiding or showing a group with children would not update the children properly.
• Sprinklers and nozzles latch in cases not intended by PyroSim's CTRL logic.
• In some cases, unsupported records were not being added to the additional records section on import.

New Features:

• Added several undocumented FDS output quantities found only in examples and the FDS source code (e.g. HYDROGEN, SOOT).
• Improved sprinkler write format for non-dry pipe sprinklers.
• PyroSim now permits devices, profiles, and reactions to be imported without an ID.
• It is now possible to set the temperature of surfaces, particles, and gauge heat flux devices to ambient by typing TMPA in the temperature field.
• It is now possible to set the surface temperature of burner surfaces.
• Thermocouples can now be created directly from the Devices menu.

Changes in Patch 2007.1.0925 RC2

• Fixed a bug that caused PyroSim to crash when creating the first grid for a model that contained nested empty groups.
• The Open Legacy PSM File warning now allows users to cancel the Open operation.
• Fixed a bug that caused PyroSim to crash when loading very old models that contained unitless values.
• Improved performance when deleting objects in large models.
• Flammable solids with constant HRR from PyroSim 2006, were converted into burner surfaces but are now converted into heater/cooler surfaces.
• Fixed a tree expansion bug that occurred when the model was reset.
• Grids can now be selected with the selection box.
• FDS CSV results that do not include an integer on the first line can now be shown in PyroSim. Results that include the integer can still be displayed.
• Fixed a bug that was causing latching to be handled incorrectly on control and device outputs that are inverted.
• Updated included FDS version to RC8 rev 697.
• Fixed a bug that prevented PyroSim from importing CTRL records containing AT_LEAST and ONLY records.
