I’d like to request someone make a correction to the FLD documentation. The flag definitions are contradicting each other in the pair_style lubricate doc. There are several points where it says to the effect “0/1 to include/exclude.” Just reverse the include<->exclude, to be consistent with the rest of the document.
Is it also possible to refer to Kumar’s thesis, since it is public record. Their publication in Phys Rev E does not discuss the modelling for their approximation of the far-field interactions. I have only found this discussion in his thesis, which he pointed me to.
