I am interested to generate some configurations from MD simulations which include the presence of strong magnetic field. Does anyone know any software that has some functionality to do this?
There is certainly Lammps, which has a fix efield that allows you to apply electric field in your chosen cartesian direction. But I am not sure if it works for your purposes. You can play around with it to see.
Actually that depends on what you're trying to achieve with the simulation. Generally speaking the magnetic field is not much different from the electric field, therefore the effect can be incorporated with small changes to
fix efield in LAMMPS to account for different constants. In fact, this was what we did in a paper some time ago. However, the effect of the external magnetic field on magnetized particles is just a torque, and hence it makes sense to apply the torque only to spherically asymmetrical particles.
