March 2024 update for DEMO "SAND - software for generation of packed beds"

The SAND code for packed bed generation has been uploaded to Mendeley Data and is available for free use by the scientific community. This Python-based open-source code, developed by the authors, aims to streamline the process of generating packed beds for various applications, particularly within computational fluid dynamics (CFD) simulations. Researchers and practitioners can access the code on Mendeley Data, where it is readily available for download and implementation in their studies and projects. The SAND code offers a user-friendly interface and efficient algorithms to facilitate the generation of packed beds, addressing the limitations of existing software tools. We encourage researchers to explore and utilize the SAND code to enhance their research endeavors in the field of packed bed simulations.用于生成填充床（packed bed）的SAND代码已上传至孟德莱数据集（Mendeley Data）平台，可供科研界免费使用。本代码由本文作者团队开发，为基于Python的开源代码，旨在简化面向各类应用场景的填充床生成流程，尤其适用于计算流体动力学（Computational Fluid Dynamics, CFD）模拟领域。科研人员与行业从业者可在孟德莱数据集（Mendeley Data）平台获取该代码，其可便捷下载并直接应用于相关研究与项目实践。SAND代码配备用户友好的交互界面与高效算法，可有效助力填充床生成工作，弥补了现有软件工具的局限性。我们鼓励科研人员探索并利用SAND代码，以推进其在填充床模拟领域的研究工作。
