<div>Hi all,</div>
<div><br>
</div>
<div>I am trying to model a solid object moving in an initially motionless gas in a cartesian grid with a constant gravitational acceleration.</div>
<div>I am not quite sure how to model this solid object. <br>
</div>
<div>From what I understand I could try with the multitype EOS but I am not quite sure what to use as an appropriate EOS for my object, or I could try with active particles as mentioned in the user's guide?
<br>
</div>
<div>Any of you have tried something like this with FLASH?</div>
<div><br>
</div>
<div>Best,</div>
