UrQMD
UrQMD (Ultra relativistic Quantum Molecular Dynamics) is a fully integrated Monte Carlo simulation package for Proton+Proton, Proton+nucleus and nucleus+nucleus interactions. UrQMD has many applications in particle physics, high energy experimental physics and engineering, shielding, detector design, cosmic ray studies, and medical physics. Since version 3.3, an option has been incorporated to substitute part of the collision with a hydrodynamic model. UrQMD is available in as open-source Fortran code.{{citation needed, date=October 2008 UrQMD is developed using the FORTRAN language. Under Linux the gfortran compiler is necessary to build and run the program. The UrQMD model is part of the GEANT4 simulation package and can be used as a low-energy hadronic interaction model within the air shower simulation code CORSIKA CORSIKA (COsmic Ray SImulations for KAscade) is a physics computer software for simulation of extensive air showers induced by high energy cosmic ray ...

CORSIKA
CORSIKA (COsmic Ray SImulations for KAscade) is a physics computer software for simulation of extensive air showers induced by high energy cosmic rays, i.e. protons and atomic nuclei, as well as Gamma rays (photons), electrons, and neutrinos. It may be used up to and beyond the highest energies of 100 E eV. In the current version the program utilizes the hadronic interaction models EPOS, QGSJET, and DPMJET, which are based on Gribov-Regge theory, and SIBYLL based on a minijet model for high energies. Hadronic interactions at lower energies are described either by the GHEISHA module, by FLUKA, or by the UrQMD model. Electromagnetic interactions are treated by an adapted version of the EGS4 code, customized by including the Landau–Pomeranchuk–Migdal effect relevant at higher energies. It can be used to simulate the generation of Cherenkov radiation, radio emission ( Askaryan radiation), and atmospheric neutrinos. A complete rewrite of CORSIKA in C++ named CO ...

Open-source Software
Open-source software (OSS) is Software, computer software that is released under a Open-source license, license in which the copyright holder grants users the rights to use, study, change, and Software distribution, distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative, public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to online collaboration, participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2024 estimate of the value of open-source software to firms is $8.8 trillion, as firms would need to spend 3.5 times the amount they currently do without the use of open source software. Open-source code can be used for studying and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physics Software
Computational physics is the study and implementation of numerical analysis to solve problems in physics. Historically, computational physics was the first application of modern computers in science, and is now a subset of computational science. It is sometimes regarded as a subdiscipline (or offshoot) of theoretical physics, but others consider it an intermediate branch between theoretical and experimental physics — an area of study which supplements both theory and experiment. Overview In physics, different theory, theories based on mathematical models provide very precise predictions on how systems behave. Unfortunately, it is often the case that solving the mathematical model for a particular system in order to produce a useful prediction is not feasible. This can occur, for instance, when the solution does not have a closed-form expression, or is too complicated. In such cases, numerical approximations are required. Computational physics is the subject that deals with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GEANT (program)
GEANT is the name of a series of simulation software designed to describe the passage of elementary particles through matter, using Monte Carlo methods. The name is an acronym formed from "GEometry ANd Tracking". Originally developed at CERN for high energy physics experiments, GEANT-3 has been used in many other fields. History The very first version of GEANT dates back to 1974, while the first version of GEANT-3 dates back to 1982. Versions of GEANT through 3.21 were written in FORTRAN and eventually maintained as part of CERNLIB. Since about 2000, the last FORTRAN release has been essentially in stasis and receives only occasional bug fixes. GEANT3 was, however, still in use by some experiments for some time thereafter. Most of GEANT-3 is available under the GNU General Public License, with the exception of some hadronic interaction code contributed by the FLUKA collaboration. GEANT-3 was used by a majority of high energy physics experiments from the late 1980s to the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU Compiler Collection
The GNU Compiler Collection (GCC) is a collection of compilers from the GNU Project that support various programming languages, Computer architecture, hardware architectures, and operating systems. The Free Software Foundation (FSF) distributes GCC as free software under the GNU General Public License (GNU GPL). GCC is a key component of the GNU toolchain which is used for most projects related to GNU and the Linux kernel. With roughly 15 million lines of code in 2019, GCC is one of the largest free programs in existence. It has played an important role in the growth of free software, as both a tool and an example. When it was first released in 1987 by Richard Stallman, GCC 1.0 was named the GNU C Compiler since it only handled the C (programming language), C programming language. It was extended to compile C++ in December of that year. Compiler#Front end, Front ends were later developed for Objective-C, Objective-C++, Fortran, Ada (programming language), Ada, Go (programming la ...
