TecDescription Focus 2021 R2 (2021.2.0.7461)

TecDescription Focus 2021 R2 (2021.2.0.7461) Release Notes
TecDescription Focus 2021 R2 has many of the improvements of TecDescription 360 2021 R2, with a few exceptions.
What is new in TecDescription Focus 2021 R2
- Contour Legend Header now allows user-supplied text - You no longer need to edit variable names to change the header text. The header text supports the inclusion of auxiliary data and other text modifiers supported by TecDescription Focus. This change also resulted in a reorganization of the macro language. Old macros are backward compatible but should be updated to use the new API call.
- Data>Alter>Specify Equations dialog now has a toggle to Ignore Divide by Zero Errors - When toggled on, equations will continue to process even if a divide by zero occurs. Details on resulting values are included in the User's Manual and Scripting Guide.
- Visibility of zones is now configurable for transient data - This fixes a problem in which zones which "disappear" during a transient simulation were still being displayed when they shouldn't have been. Users of TecIO can use Common.TransientZoneVisibility to set the default behavior in data files.
- Support for logarithmic time scales - Previously TecDescription Focus would treat all time scales as linear, incorrectly clustering early solution times causing multiple solution times to be rendered simultaneously. The solution time clustering options may also be used to customize solution time spacing for cases where the default settings don't group time steps together as expected. This feature is currently only available via macros. Adjustments to these values are retained in layout files.
Bug Fixes and Enhancements
- Reduced the amount of temporary disk storage required by 99.6%! TecDescription Focus' Load-On-Demand feature would previously unload certain data to temporary storage on disk when the RAM limit (as defined by Load-On-Demand settings) is reached. Disk speed has not kept up with CPU performance, so recomputing these values has proven faster than relying on disk access. In one test - creating a movie file with simulation results which consisted of 133Gb of data spread over 720 timesteps - we saw temporary storage requirements drop from 70Gb down to only 307Mb an improvement of 99.6%! The reduced disk access also resulted in anywhere from a 3.8% to 19.7% performance improvement, depending on Load-On-Demand settings.
- Improved performance when initializing contour levels for transient datasets with a very large number of zones per time step. In testing we saw a 23.8x speed improvement over 2021 R1 for a Description3D dataset consisting of 65004 zones. Below are the timing results to load the data, render a slice colored by Rho, change the slice to be colored by Energy. These tests were done on a Windows 10 machine with40 logical cores and 128Gb RAM. Note that this performance improvement is more a function of the number of zones in the dataset than the size of the grid.

- Fixed intermittent crash when TecDescription Focus starts up on Windows.
- Fixed issue with AVI movie export where some frames were inverted or had odd coloring artifacts. AVI export now relies on FFmpeg for encoding (similar to MP4 and WMV exports).

- Fixed issue where Axis Edit>Reset Range commands were not getting recorded in macros.
- Fixed issue where self-referential equations (e.g. {X} = {X} + 1) could result in an incorrect value when Minimize Memory Use was enabled.
- All TecDescription products now require Reprise License Manager 11 or newer.

TecDescription Focusis engineering Descriptionting software with extensive XY, 2D and 3D capabilities. It is designed more for measured field data, performance Descriptionting of test data, mathematical analysis, and engineering Descriptionting in general. TecDescription Focus is based on TecDescription 360 EX, TecDescription's flagship visualization product, and has much of the same power. One of the key differentiators between TecDescription Focus and TecDescription 360 is that TecDescription Focus does not support CFD data formats, CFD analysis, and transient data.
