[FLASH-USERS] Moving solid object in flash4

[Sylvain Turcotte]

Hello Ryan,

Thanks for your reply!
I have used the wind tunnel approach before but, unfortunately, it don't believe it will give us exactly what we want in this case.

Best,
Sylvain

Hi Sylvain,

I've never tried to do this but would it be perhaps easier to do a wind tunnel setup (move to the frame of your falling object) with the solid object represented as boundary zones? I believe the latter is controlled by "BDRY_VAR" index of the pointer to the solution data.

Hi all,

I am trying to model a solid object moving in an initially motionless gas in a cartesian grid with a constant gravitational acceleration.
I am not quite sure how to model this solid object.
>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?
Any of you have tried something like this with FLASH?

Best,
Sylvain
