Hi everyone! I’m starting to study the sph method in lammps and have a beginners question: I’m looking at the heat conduction cpp file and the formula is very different from the one that can be derived theoretically (see for example http://cg.informatik.uni-freiburg.de/intern/seminar/particleFluids_Monaghan%20-%20SPH%20-%202005.pdf, equation 7.4). Is someone familiar enough with the derivation of the lammps cpp code to explain that to me? I’ve been trying for a while and can’t seem to get the same equation.
Thanks a lot and sorry for the inconvenience!
I suggest you send an email to Georg (CCd) who wrote the USER-SPH package.
