I am trying to preform a CFD study on pulmonary drug delivery analysis through human body. So, for that study I want to make use of OpenFOAM to solve for the behaviour of nano particles drugs, but I am not sure that this will workout in OpenFOAM. Even though alternative sources like ANSYS and LAMPPS are there for the nano particle study I want to make use of OpenFOAM. So can anyone please suggest me any study material or solver used for Nano particle fluid flow using OpenFOAM.
