Preface to the Special Issue on "Modelling and Simulation in Engineering".

The paper by K. Zhang et al. [[6]] studies calcium leaching in hydraulics applications, formulated as an inverse problem, which is studied using genetic algorithms and the finite element method. The continuing achievements in Information Technology and Computer science in recent decades provide new tools for engineers in the design of devices and systems, with significant advances both in numerical and in analytical methods of analysis. 10.3390/math10101619 3 Feng F., Yuan M., Xia Y., Xu H., Feng P., Li X.
