A new GROMOS after 15 years

Yesterday, after 15 years a new official release of GROMOS (in C++) has seen light of the day. All informations are available on this website: www.gromos.net
GROMOS11 relies on 30 years of scientific research for biomolecular simulation (soft matter). Primarily, in contrast to other packages it has to suit the needs of the scientific community.
The models (force-fields) have been further developed over decades and are highly specialised for proteins, sugars and lipids. In contrast to simpler models, they are fitted on experimental thermodynamical data of liquids and not on structures in vacuum.
We from xirrus have developed with GROMOS96, respectively worked on its models earlier and own a life long license.

Tensile strength of polymer

Organic molecules, such as polymers or biopolymers can partly cover enormous tensile strengths. In the shown example of a graphene nanoflake, which has been tested on tensile strength, it has been more than 250 times bigger than for steel!

This strong property shall be used in a composit material, to substantially change its properties compared to the pure material.
The strength of the molecule has its origin in the chemical bond. Material cracks do not open normally within molecules, but between molecules. Therefore the intermolecular forces are an important part of the models. It is possible, to check virtually polymers or its composits on the tensile strength without knowing the macroscopic material properties in advance.

combustion and flow solutions GmbH

methods: CFD

  • For most applications, the calculations are done with commercial packages Star-CD and GT-Power, which have been enhanced by our own subroutines.
  • Customized solutions are applied as well.
