The McStas[1,2] neutron ray-trace simulation package is a versatile tool for simulating neutron instruments and experiments alike. McStas was first released from RISØ in 1998[3] and has since grown to become a widely accepted open source software, backed by an international collaboration and a large user community.
McStas applies Monte Carlo and ray-tracing methods for transport of neutrons...

VITESS is an open-source software package for the simulation of neutron instruments and virtual neutron experiments [1]. It allows simulating practically all components used in current neutron scattering instruments and thus simulating all kinds of instruments at existing neutron sources. Instruments are usually first designed using a Graphical User Interface and then optimized using scripts...

The neutron ray-tracing code SIMRES has been developed since 1990th from the program Re-sTrax for three-axis spectrometer [1] into a general instrument simulation program [2]. Its ar-chitecture is different from the versatile simulation package McStas [3]. SIMRES is a desktop application designed for interactive work with a virtual instrument constructed from a given list of beamline...
