[gmx-users] Simulating Aluminum Oxide Particle in Water

[Bill Evans]

Hi,
 
I am new to using GROMACS but I have been successful in using it to
perform some non-equillibrium dynamics to calculate the thermal
conductivity of water. I would now like to model an Aluminum Oxide
(Al2O3) particle-water interface. 
 
I could really use help on how to create the topology for a particle of
Al2O3 of about 10 nm diameter to be inserted in a box of water. I have
searched the archives but have not found anything on this. I understand
that GROMACS is mostly used to simulate organic molecules but I do no
see why it cannot be used for crystalline materials. If so, is there an
appropriate force field in GROMACS for crystalline materials,
specifically AL2O3?
