Reply To: Not clear which version of Shan Chen model is implemented

[Jendrik Weise]

I believe the issue with 1. may be the following: internally(elements.h#1095), the Guo forcing adds the term force/2 for each lattice individually, however normally this should happen before the averaging(at least for the Shan-Chen forces), meaning that in a correct explicit forcing implementation all fluids at a given location have the same equilibrium velocity. I have yet to address that potential issue in the code myself so take the above results with a grain of salt.
