PyroSim 2016.1

What's New

This version of PyroSim is designed for FDS version 6.4.0 and Smokeview version 6.3.6. It uses version 1.8.0_60 of the Java VM.

Changes since PyroSim 2015.4.1214:

• Updated FDS to version 6.4.0.
• Updated Smokeview to version 6.3.6.
• Added import support for FBX files.
• Added import support for OBJ files.
• Improved lighting and outline displays of imported objects.
• When using the Run as Cluster option, PyroSim no longer requires the Unlimited Cluster Add-on to run on more than one additional machine.
• Sprinklers can now be used to activate other objects by specifying them in a control.
• Sprinklers, nozzles, sprinkler links, and detectors can now be used as ramp input.
• Time devices can now be created directly using the New Time Device menu option.
• Any device that outputs a quantity, such as a gas-phase device or heat detector, can now have an input control specified that freezes the output of that device.
• Devices now have an Advanced tab to make it possible to add custom records for the DEVC record and the PROP record.
• VENT, OBST, and HOLE records generated by PyroSim now have an ID to improve integration with custom record entry.
• Added parser support for the HOLE parameter MULT_ID.
• Simulations that use MPI will now by default use only one OpenMP thread. This can be edited in the OpenMP Environment dialog.
• Simulations that do not use MPI will now by default use only two OpenMP threads. This can be edited in the OpenMP Environment dialog.
• PyroSim now attempts to detect vents that will collapse to a line or point when snapped to the simulation mesh and issue a warning.
• Mesh cell counts are now displayed in the tree.
• PLOT3D data output specification has been centralized in the PLOT3D Data dialog and a button has been added to specify common quantity sets.
• Usability improvements for the Group, INIT Region, and Import dialogs.
• Fixed a bug where rotated walls were being converted to blocks as a single bounding box rather than a string of smaller blocks.
• Fixed a bug where deleted surfaces could be replaced with the HVAC surface.
• Fixed a bug where previously disabled vents were enabled after loading in a newer version of PyroSim.
• Fixed a bug where custom records from PSM files created by previous versions of PyroSim were sometimes being dropped.
• Fixed a bug where a single sprinkler connected to a dry pipe would activate without a delay.
• Fixed a bug where very small floating precision errors in vent locations could cause vents to be ignored by FDS.
• Fixed several bugs that could cause PyroSim to crash.
• Fixed a bug where, to copy an angled wall, it was necessary to explicitly select the containing mesh.
• Fixed a bug where the Open Mesh Boundary command would create vents for disabled meshes.
• Fixed a bug where CAD import would incorrectly create surfaces of type Adiabatic.
• Fixed a bug where PyroSim could create duplicate device IDs for statistics objects.
• Fixed a bug where Viewpoints created with the Roam tool could not be recalled in Smokeview.

Changes in Patch 2016.1.0419

• Fixed a bug that could cause PyroSim to crash when editing Simulation Parameters.
• Updated translations for non-English locales.

Changes in Patch 2016.1.0425

• Fixed a crash that could occur when writing an FDS input file of a model including statistics regions whose volumes are dependent on a mesh.
• Fixed a bug that could corrupt geometry when using the paint tool.
