Dear gromacs users
I want to simulate gold nanoparticle by golp force field that needs to
determine virtual sites for Au atoms. I read gromacs manual section 5.2.2 and
4.7
but it is not clear that how can I do it and .also I read virtual site tutorial
for CO2 but it is for a 3 atomic molecule and I have a crystal by many
atoms. I have a pdb file of my nanoparticle contain 600 atoms. How can
specify their virtual site? Should I do it by hand? Do you know any
command or software that can help me?
You'll have to define how the virtual sites need to be constructed. There are
many ways to do so. See manual section 4.7, especially Figure 4.16.
