"FEFLOW软件是DHI-WASY公司开发的一款强大的地下水和溶质迁移模拟系统,主要用于地质环境和工程领域的数值模拟。用户手册详细介绍了软件的各个功能模块,包括用户界面、地图处理、空间初步划分、有限单元网格、问题设定、参数可视化、参数赋值、模拟运行以及结果评价等。此外,还特别提到了观测点和局部浓度图的使用,以及水量平衡分析的功能。" 在FEFLOW6这款软件中,用户可以通过观测点来监测地下水模型中的关键参数,如水头、浓度和水压。观测点的数据可以以图表形式显示,便于分析模拟过程中的变化趋势。局部浓度图则帮助用户理解溶质在特定区域的分布情况,这对于评估污染扩散和治理策略至关重要。 水量平衡分析是FEFLOW的一项重要功能,它允许用户跟踪模型区域内流体和溶质的进出通量。通过水量平衡面板,用户可以选择流体通量和溶质通量进行分析,以确保模型的物理一致性。激活水量平衡分析后,软件将计算各边界类型、源/汇项的流量,并显示储水量的变化率,从而帮助用户检查模型的准确性。 此外,FEFLOW提供了丰富的用户界面定制和地图处理功能。用户可以根据需求自定义工作界面,处理和导入地图数据以适应各种地理参考坐标系。软件还支持空间初步划分,允许用户定义模型的几何特征,并通过网格生成算法进行有限单元网格的创建和编辑,以适应复杂的地质结构。 在问题设定部分,用户可以选择不同类型的地下水流问题和求解方法,包括但不限于稳定态和非稳定态模拟。同时,FEFLOW提供了多种参数赋值方式,如常数值、时间序列数据、地图数据和查找表赋值,以适应不同情境下的数据输入需求。 在模拟运行和结果评价阶段,用户可以监控模拟的收敛性,查看观测点的结果,进行水量平衡分析,以及含量分析等。软件还支持流线和迹线的绘制,帮助用户直观理解流体运动路径。最后,FEFLOW还具备动画和视频输出功能,方便用户以动态方式展示模拟结果,增强报告的可视化效果。 FEFLOW是一款全面且功能强大的地下水模拟工具,其强大的功能和用户友好的界面设计使得复杂地质环境下的水文地质问题分析变得更为便捷和准确。
