PyroSim 2022.2

What's New

This version of PyroSim is designed for FDS version 6.7.9 and uses version 1.8.0_302 of the OpenJDK Java VM.

Changes since PyroSim 2022.1.0422:

FDS Updates

• Updated FDS to version 6.7.9 and Smokeview to version 6.7.21.
• Added support for defining flow measuring devices as prescribed in FDS 6.7.8 and beyond.
• Added support for PID, Percentile, and ATan math control functions.
• Added missing property options to the Coloring tab of the Edit Particles Dialog.
• Zone geometry is now based on a single 3d point as required in FDS 6.7.8 and beyond.
• Added support for HRR_GAS_ONLY &DUMP parameter.
• Added support for measuring Favre Average and Favre RMS for Temporal Statistics.
• Added the ability to create a linear array of devices for Spatial Statistics.
• Added support for measuring Centroid values for Spatial Statistics.

General Improvments

• Reduced time to select objects with lots of manipulation handles.
• Greatly improved tool snapping performance and responsiveness in complex models.
• Improved picking performance in the 3d/2d views in complex models.
• Fixed a bug where the selection tool might unexpectedly select an object or select the wrong object.
• Fixed a bug where the drawing, manipulation, and transform tools might snap the cursor to hidden edges or points.
• Fixed sluggishness in the appearance dialog when working high-resolution textures.
• Fixed a bug where the appearance dialog might not save changes.
• Fixed a bug where the transform tools would snap to the handles of the object being transformed.
• Fixed a bug where custom species viscosity and diffusivity ramps displayed inputs of Time instead of Temperature.
• Fixed a bug where showing or hiding an animated geometry set from FDS would not update the timeline.
• Fixed a bug where object outlines might become incorrect when objects are hidden.
• Fixed a bug where the application might hang for a long time while hovering the cursor in the 2d/3d views.
• Fixed a crash that could occur when enabling or disabling vertex buffers in File->Preferences->Rendering.
• Fixed a bug where the camera might jump unexpectedly and the roam tool acts like the left mouse button is being held after using a transform tool.

Changes to Results:

General Improvements

• Added support for showing and hiding individual scene objects in Results.
• Added a visualization of the maximum Pressure and Velocity errors in a simulation.
• Improved tool snapping performance in complex models.
• Improved performance when using the occupant follow camera when there is complex scene geometry visible.
• Added Collapse all and Expand all buttons to the navigation view.
• Fixed a bug when loading an SMV file where the HRRPUV cutoff for Smoke/Fire would be set to 600 kW/m^3 instead of that specified in the SMV file.
• Fixed a bug where the selection tool might sometimes select the wrong objects.
