PyroSim 2018.2.0730

What's New

Changes to Results include creating views and section boxes, unit switching for concentration and temperature, and many other improvements.

This version of PyroSim is designed for FDS version 6.6.0. It uses version 1.8.0_172 of the Java VM.

Changes since PyroSim 2018.1.0417:

• Added support for specification of complex reaction stoichiometry.
• On laptops with a discrete GPU, PyroSim will try to use the discrete GPU rather than the integrated Intel graphics.
• Added GPU information to the Preferences and About dialogs.
• Fixed a bug that could cause an incorrect input to be written for device parameter SPRAY_ANGLE.
• Fixed a bug that could cause localized versions of PyroSim to crash when loading PSM files created with PyroSim 2012.1 or earlier.
• Fixed a bug that caused dialogs with tables (e.g. Animated 3D Slices) to close rather than inserting a new line when pressing enter.
• Fixed a bug that prevented deleting REAC_FUEL after it was added to the model.
• Fixed a crash that could occur importing FBX, DAE, and OBJ files if the file path contains certain characters.
• Fixed a bug that could cause the first line of an FDS file to be skipped when importing into PyroSim if the file was encoded using a Unicode byte-order marker (BOM).
• Fixed a bug that caused lumped species added from library files and copy / paste to not reference all component species.

Changes to Results:

• Views, tours, and section boxes can now be created directly within Results. This data can also be exchanged between results using an import feature.
• Automated the creation of screenshots (still images) from various views and playback times.
• Added support for visualization of cell-centered 2d and 3d slices.
• Added the ability to change the unit for concentration from mol/mol to ppm and the unit for temperature from °C to °F.
• Added the ability to show a Calendar date and time in the 3D View in addition to time offset.
• Occupant paths can now be colored by group or by group template.
• Improved rendering performance for occupant paths.
• Activating occupant paths can now be cancelled if loading times are slow.
• Added toolbar button to reset the view to the current selection.
• Pressing Enter now commits spinner field values.
• Added the ability to specify a 2d slice through a 3d dataset as an axis-aligned value.
• On laptops with a discrete GPU, Results will try to use the discrete GPU rather than the integrated Intel graphics.
• Added GPU information to the Preferences and About dialogs.
• Fixed a bug where cell-centered boundary results would display incorrectly.
• Fixed a bug that would cause results data to appear shrunk toward the center of the mesh by a half mesh cell when rendering the following results types: Smoke, fire, volumetric 3d datasets, 2d slices through 3d datasets.
• Fixed a bug using the compatibility renderer for volumetric 3d datasets that could cause gaps in the rendering.
• Fixed a crash when displaying FDS objects that use multiple surfaces as outlines.
• Fixed a bug that could cause Results to use the wrong texture origin.
• Fixed a bug causing occupant paths to not be clipped by the active section box.
• Fixed a crash that could occur when plotting a 2d slice through a 3d dataset using the compatibility renderer.
• Fixed a bug where the application might hang when trying to use the FDS results action, "Cache results for smooth playback".
• Fixed a bug that caused the slice properties editor to reset the slice value when editing the offset.
• Fixed a bug where occupant contours sometimes show data when the playback time is outside the occupants' time range.
• Fixed a bug causing occupant paths to not refresh along with other results while the Pathfinder simulation is ongoing.
• Fixed a bug where the wrong occupant paths might be showing if the Pathfinder results is replaced with another result set.
• Fixed a bug where occupant contours might not be colored correctly when the colorbar is hidden.
