Aspherix(R) Calibration Version 6.3.1 Release Notes
###################################################
Minor Improvements and Bugfixes:
- Removed a false-positive warning about old particle_distribution
syntax being used
Aspherix(R) Calibration Version 6.3.0 Release Notes
###################################################
Main Improvements:
- Convert the uniaxialCompression template to natural language
Minor Improvements and Bugfixes:
- Improved error messages in case a data file cannot be read properly
- Fixed a small issue in command line argument parsing
- Improve performance of uniaxialCompression template for small particles
- Fixed issue in uniaxialCompression template when using yielding test
for periodic setups

Aspherix(R) Calibration Version 6.2.0 Release Notes
###################################################
Minor Improvements and Bugfixes:
- Add cgs units and polydisperse flags to: bulkDensityTest, staticAngleOfRepose and shearCellSchulzePeriodic
- Improve uniaxial compression template
- Improve settling behaviour in staticAngleOfRepose template

Aspherix(R) Calibration Version 6.1.4 Release Notes ################################################### No changes Aspherix(R) Calibration Version 6.1.3 Release Notes ################################################### Minor Improvements and Bugfixes: - Update of bulkDensityTest, ErgunTest and volumeFracTest Aspherix(R) Calibration Version 6.1.1 Release Notes ################################################### Minor Improvements and Bugfixes: - If more than one template is used for calibration, the unscaled individual quality functions of each template are also written to conv.dat and qf_history.dat Aspherix(R) Calibration Version 6.1.0 Release Notes ################################################### Main Improvements: - Aspherix(R) Calibration is now able to natively run Python scripts as calibration cases Minor Improvements and Bugfixes: - Quality function of shearCellSchulzePeriodic can now be weighted by normal stresses. This increases the weight of points with low normal stress. - Aspherix(R) Calibration now throws an error if a param_fixed is used as target parameter (previously this was just a warning). - Bugfix in command line argument parsing: mpi options can now be properly set via the command line - improved stability of postprocessing in static angle of repose - some minor improvements in ergunTest and volumeFracTest

Aspherix(R) Calibration 6.0.3 Release Notes
###########################################
Minor Improvements and Bugfixes:
- Convert the inclinedWall test to natural language and add compatibility
to adaptive model
Aspherix(R) Calibration 6.0.2 Release Notes
###########################################
Main Improvements:
- shearCellSchulzePeriodic now uses a variable check interval during the
insertion phase. This significantly decreases simulation time when small
timesteps have to be used.
Minor Improvements and Bugfixes:
- Fixed a bug in runInit.sh of shearCellSchulzePeriodic
Aspherix(R) Calibration 6.0.0 Release Notes
###########################################
Main Improvements:
- There is now a third parameter type param_tracking. This allows to update a
parameter depending on another one, so the dimensionality of the calibration
can be easily reduced.
Minor Improvements and Bugfixes:
- inclinedWall can now also run in parallel, has improved performance for wide
particle distributions
- Improved readability of periodic shear cell template
- Aspherix(R) Calibration now detects which MPI distribution is used, and
optimizes the default MPI command line flags depending on the version
- fixed a bug that would cash Aspherix(R) Calibration if command line arguments
were given in a certain order
Version 5.4.X

Release notes
Aspherix(R) Calibration 5.4.1 Release Notes (December 2021)
###########################################################
Main Improvements:
- There is now a -single-iteration command line argument. This is useful to
test calibration setups: first run initialization with -init-only, then run
a single iteration with -use-init -single-iteration
Minor Improvements and Bugfixes:
- The -np command line argument now takes precedence over NPROC in the input
script, as stated in the documentation
- Fixed several problems connected to the new particle density handlingd
- Removed time step calculation from shearCellSchulzePeriodic, it now uses
the calculated/user-defined timestep like all the other templates.
Aspherix® Calibration 5.4.0 Release Notes (Release in November 2021)
####################################################################
Main Improvements:
- We added templates to calibrate drag-related properties for coupled
simulations with CFDEMcoupling (Linux only)
- A new scalable rotating drum template is available
- Some of our templates now support multisphere particles:
* staticAngleOfRepose
* rotatingDrum
* bulkDensityTest
* volumeFractionTest
* ergunTest
- Users can now create their own calibration templates. See the docu section on
user-defined templates for more information.
Minor Improvements and Bugfixes:
- The scaleweight parameter can now be used in parameter_overrides to scale the
quality functions of templates. This is useful in run mode single when the
absolute values of the quality functions differ a lot.
- oscillatoryRheometerBurgers can now be run in parallel; the angular
frequencies are being spread over the processes (only on Linux in runMode
shellScript)
- Fixed a bug that caused a segfault in the quality function of
staticAngleOfRepose
- if a case fails, the last 10 lines of the log file are written to terminal
- several improved error messages
