<div dir="ltr"><div>Hi,</div><div> My name is Saurabh Sawant. I am a graduate
student at UIUC. I am sorry I couldn't complete my previous message.
Here it is:<br></div><br><div>Now I have used micron sized active dust particles in my
simulations and I am trying to move them using some local hydrodynamic
force. I know the equation of the force and I can probably get the exact
force at the particle location in a particular direction by
interpolating the grid macroparameters. My question is: How do I make
the particles experience this force?<br></div><div><br></div><div>
If I understand correctly such a force cant be categorized as long
range or short range since it is not due to the effect of other
particles in the flow field. It's the effect of flow field on to the
particle. <br></div><div>I will need to implement a force in terms of
acceleration experienced by particle and the same way an ion experiences
acceleration due to Lorentz force right? Is there any other obvious way
to make this change?<br></div><div>Your help is much appreciated.</div><div><br></div><div>-Saurabh<br></div></div>
