Correction: Ungson, Y. et al. Filling of Irregular Channels with Round Cross-Section: Modeling Aspects to Study the Properties of Porous Materials. Materials 2018, 11, 1901

The authors have found two errors in the paper published in Materials [1]. The errors appear in the second paragraph of the Introduction section.

The authors wish to make the following corrections (in both formulas of the paragraph) to this paper:

“In the two-dimensional space, the maximal packing density for identical circles is given by $\pi /\left(2\sqrt{3}\right)\approx 0.9069$ [2]. This density is reached on square and hexagonal periodic lattices. In 1611, Johannes Kepler conjectured that in the 3D space, both a face-centered cubic packing (fcc) and a hexagonal close packing (hcp) of congruent spheres give a density of $\pi /\left(3\sqrt{2}\right)\approx 0.74048$.”

These changes have no material impact on the conclusions of the paper. The authors would like to apologize for any inconvenience caused to the readers by these changes.
