Improved wetting model for the prediction of topography and dimensionality of superomniphobic surfaces

This code calculates the contact angle formed between a sessile drop of an arbitrarily defined liquid and a rough surface based on our improved Cassie-Baxter wetting model (https://doi.org/10.1088/2051-672X/ab9419). The topography of the surface needs to be predefined into the input file and may be any of the types: a) 2D pillars, b) fibers, c) sinusoids, d) 3D pillars. Although, theoretically, our model can be applied to topographies with arbitrarily large multiplicity, here the code was devised such that it considers up to three-level topographies hierarchically placed on top of one another. In the "Input" directory, three input files are given for single, two-level and three-level topographies, respectively. In multilevel topographies, the above-mentioned topography types may be combined at will. So, for example, we may have a three-level topography with sinusoidal pulses as the coarser level, fibers as the middle-level and 2D pillars as the finest level. Similarly, two-level and single-level topographies are also possible. The definitions of the multiplicity level and topography types proceed in the input file.

本代码基于我们改进的卡西-巴克斯特（Cassie-Baxter）润湿模型（https://doi.org/10.1088/2051-672X/ab9419），可计算任意设定液体的固着液滴与粗糙表面之间形成的接触角。表面形貌需预先定义并写入输入文件，支持的形貌类型包括：a) 二维柱体，b) 纤维结构，c) 正弦型结构，d) 三维柱体。尽管理论上本模型可适用于任意复杂度的形貌，但本代码仅支持对分层堆叠的最多三级形貌进行计算。在"Input"目录下，分别提供了适配单级、两级及三级形貌的三份输入文件。对于多级形貌，可任意组合上述各类形貌类型。例如，可构建三级形貌：最粗层级为正弦脉冲结构，中间层级为纤维结构，最细层级为二维柱体。同理，两级及单级形貌也可实现。输入文件中会对多重性层级及形貌类型的定义进行详细说明。
