Re: [ESPResSo-users] Linking to external program

[Andrew Jewett]

I hesitate to post this here.  I am currently a LAMMPS users, I might
use ESPRESSO/ESPRESSO++ in the future.  So I hope someone else will
reply with a more useful answer which is specific to ESPRESSO, because
I'm curious too.

There is an effort to merge LAMMPS with OpenFOAM.  Here are some links:

Lastly, (just in case you weren't aware of this), in the low Reynolds
number limit, assuming the fluid is at rest, you can include
hydrodynamic effects efficiently using the Oseen tensor.  (See
attached equations mostly stolen from Doi and Edwards.)  I am under
the impression that ESPRESSO has the ability to do something like
this.  (Hopefully someone else will comment.)

Forgive the post from someone who is somewhat ignorant of ESPRESSO.
