GROMOS and Gromacs

For historical reasons these two software-packages are related, although there development has become quite different nowadays. The GRO they have common in name in both cases goes back to the origin of the University of Groningen in the Netherlands.
GROMOS was an initiative of Prof. Herman J. C. Berendsen and Wilfred van Gunsteren and was already in the version of GROMOS85 an attempt and with GROMOS87 a succes for the simulation of biological molecules. After the move of Prof. van Gunsteren to ETH Zurich the package GROMOS96 and even its current successor was developped in Zurich. GROMOS is available commercially and for a symbolic fee also to the academic world. It has been challenged by its professional application in basic sciencific research, but requests for a large amount of detailed knowledge by its users. We at xirrus know about the advantages of the models of GROMOS96 and apply them as we require. Additionally we develop our own parameter sets. Gromacs has been initiated in the more quiet phases of GROMOS-application and has been branched off as individual package completely. The focus has been set to Open Source and always speed optimisation and method implementation was in the foreground. Gromacs has like any other package its own flaws. Numerous tricks are necessary to let a complex system run as we’d like to design it. But Gromacs runs on nearly all CPU architectures without much complications when the set-up could be established.

xirrus simulation

since 2001

xirrus GmbH
simulates your complex problem based on particles

Since 2001 we transfer our natural scientific knowledge to complex problems in software development. Since 2004 we offer simulations as a service for all those, who do not own the capacity or don’t have access to in-house resources for Molecular Dynamics and other particle problems (communication networks, traffic flow, congestion phenomenon) or many more other individuals or actor systems simulations.

Benefits with xirrus
  • Security: gain relevant insight without taking risks of reality.
  • Verify: better understand and verify what experimentally stayed unclear.
  • Time is money: educated experts challenge your problems instead of fresh starters in the field.
  • Safe money: cost reductions by comprehensible results, software and simulation knowledge transfers. Ask us on short notice.
