choice multiphysics modeling tool

[GioAlle]

Hi, everybody, I wanted to ask you some advice. I would like to begin facing a numerical study aimed at the study of a generator of drops. The following topics are:
- vibration of a piezoelectric actuator inside a room containing fluid;
- fluid interaction structure, linked mainly to the observation of how the pressure varies (because of the vibration of a piezoelectric) in a room;
- process of formation of drops at a nozzle due to the effect of developed pressure profile;
- study of the aerodynamics of drops in air;
- process of loading drops for capacitive effect;
- interaction of charged drops within an electrical field.
I would like to know which are the best software to undertake this type of studies, with particular interest in the formation of the drop and everything that follows. have any of you ever interested in these phenomena so as to give me some suggestions on how to proceed?
thanks to all

It seems to me that the physics you go studying are partly uncomplicable, in the sense that not all phenomena depend on everything else.
In particular, for the coupled multiphysics problems that you cannot decouple, type formation of drops, I recommend a multiphysical solutor, especially indicated for nonconvective dominance phenomena, type comsol or elmer.
While for unmatched phenomena, especially convective type, I recommend a dedicated cfd solutor with excellent multi-phase capabilities to follow for example drops in flight, a problem that is not at all easy to treat.
the problem could be the coupling of the various things, but it is more of a process gesion problem than software itself.
It's not easy anyway. . .
