Fluorescence components have a new flag to enhance statistics/signal from low concentration materials. Work by @farhi.Union subsystem now handles 'surface physics' with the introduction of a system of refraction/reflection processes on geometry surfaces. Work by @mads-bertelsen.Union subsystem now has a functional 3D-mesh system (Union_mesh) that supports CAD style geometries. (Ascii/binary STL files and OFF files are supported. - For now only those with triangular meshing.) Work by @Lomholy.Union subsystem have been tested / improved / revised. Contributions by @tkittel and @willend in close collaboration with @mads-bertelsen.ISIS_LET by Ross Stewart and Rob Bewley, serves as test-instrument for Commodus_I3 (ISIS source model - corresponds to ViewModISIS with a different parameter interface)Multilayer_sample from Rob Dalgliesh was updated with nrepeats which allows to repeat an SLD material stack. ISIS_CRISP was updated to include this feature.TOF_PSDmonitor_toQ is a new component with built-in data reduction from Rob Dalgliesh. Uses ToF to calculate Q. Test_TOF_PSDmonitor_toQ is a basic instrument to showcase the component.conda platform which uses the
MSVC compiler is now fully functional
for all McStas code and a good part of the McXtrace code. As part of
this process a new header-file mccode-complex-lib.h
should be used by all code requiring complex numbers. (Implements
functions for e.g. +-*/ operations across platforms -
MSVC does not self implement these operations...) @willendFor all release details, please refer to the github release page for version 3.6.1
Seasons greetings from all of McStas/McXtrace - and hope you will enjoy this new release!

INHERIT)Full Changelog: https://github.com/mccode-dev/McCode/compare/v3.5.27...v3.5.32
Dear all,
McStas and McXtrace release 3.5.27 is now available.
McXtrace installation instructions are found on GitHub .
mcrun/mxrun have a new -y
switch which runs a given instrument using its default parameters.
mcplot/mxplot should now deal better with
negative / very small numbers in 'log' mode plotting.
mcgui/mxgui improved tooltips on the run dialogue.
rootmccode works with newer versions of ROOT
|P|>1.
We are now in the air with new server hardware.
Among other things this means that component mxdoc pages are back online - by popular demand!
We are in the process of upgrading the webserver for McStas, McXtrace and other sites. Please bear with us if you experience service interruptions. :-)
Dear all,
McStas and McXtrace release 3.5.24 is now available - McXtrace installation
instructons on GitHub .

The new tool is mainly written in python and thus has a lower barrier for changes in language syntax and code generation. The tool implementations mcstas-antlr and mcxtrace-antlr are thus a candidate implementations to potentially replace the classic mcstas and mcxtrace code generators in the future. Current status is thatmcstas-antlr is fully feature complete wrt. mcstas for CPU simulations and close to complete for GPU simulationsmcxtrace-antlr but basic functionality is in placemccode-antlr from conda-forge or via pipmcstas-antlr by --cogen=mcstas-antlr option in mcrunMCCOGEN field of mccode_config.json using the new Save/Edit configuration in mcgui-I${MCSTAS} to prefer ingredients fromyour local library)mcrun-antlr/mxrun-antlr tools provided directly by mccode-antlr.exeinstaller from mccode.org:
