软件简介—SoftWare Description: Geoslope Seep3D V1.15 地下水模拟

Seep3D软件将强大的交互式三维设计引入饱和、非饱和地下水的建模分析中，使用户可以迅速分析各种各样的地下水渗流工程问题。

使用Seep3D的交互式建模方法，用户可以迅速建立几何分析模型，定义好几何模型的材料特性和边界条件后，用户就可以进行求解运算，最后在三维界面内用户就可以查看诸如等值面和流线等结果了。对计算模型进行局部剖分，利用三维数据输出工具即可对任意的计算值进行快速而精确的分析。

使用Seep3D软件，用户可以把用户所分析的地下水流动问题扩展到包括如水库、水坝、流动堵塞等特殊结构模型，排水沟或井下渗流，坡面和坡底相关的流动，以及耗散障碍系统中的渗流和流动。并且，以上所提到的这些问题，都可以在一个模型中进行统一分析。

几何模型上的材料特性和边界条件可以分别定义。这样，如果用户从整个模型中删掉一些区域后，整个模型的材料特性和边界条件信息仍然适用。如果用户要在模型内加入一种新的边界条件并将它应用于模型内的部分区域，用户只需把相关信息加入一次即可生效，这样可以减少犯错。用户也可以通过定义一种材料的特性而改变整个模型的材料特性，新定义的材料特性值可以用于整个模型内所有用到这种材料的地方。

只要用户建立起几何模型并加入相关的材料特性和边界条件，就已经做好了使用Seep3D中的模型算法库进行分析的前期准备工作。Seep3D内部包含了支持线性、非线性、稳态、瞬态、自适应分析的算法求解器。

用户可以迅速地从众多的3D分析结果数据中找到用户所需要的结果。例如，用户可以对模型进行分割而产生“结果平面”，从而显示等值面、流速向量、流线等，得到所需要的各种数据。用户可以利用模型表面的所有参数作为坐标变量，在x-y坐标平面内作图，也可以将相关数据拷贝到Excel文件中进行进一步的分析。

Seep3D的交互式直观模型界面使用户快速进入各种命令格式。在3D对话框或树形对话框中，用户只需点击相关对话框，即可改变它的特性或执行相关命令。在交互式3D对话窗口中，用户可以对用户的模型进行缩放、平面处理和翻转等操作，也可以显示多重3D视窗。当在一个窗口内改变模型时，其他窗口内也发生相应的改变。

Seep3D尤其适用于所有包含三维流动的工程问题的建模分析。一个典型的应用例子就是蓄水坝下游的脱水井或小型排水沟问题中的三维流动。这种问题实际上是不能用二维模型来分析的，这就需要进行真正的三维模拟分析。另外一个典型的工程实例就是对流入方形基坑中的水流分析。

对与所有工程结构相关的真实三维渗流问题，Seep3D是一种非常理想的分析工具。

Seep3D brings the power of interactive 3D design to the world of saturated/unsaturated groundwater modeling. Using Seep3D, you can analyze a wide variety of groundwater flow problems. Construct your geometry one block at a time using Seep3D’s interactive building block approach. Specify material properties and boundary conditions on the geometry. Solve the analysis, and then visualize your results in 3D as surface contours and flow lines. Create graphical plots, and use Seep3D’s data extraction tools to quickly pinpoint any computed value.

Using Seep3D, you can extend your analysis of groundwater flow to include specific structural geometry such as reservoirs and dams, flow cutoff barriers, individual seepage drains or wells, combinations of side and down-slope flows, and infiltration and flow in waste barrier systems. All of these items can even be combined into a single model.

Building Blocks
Seep3D is based on the concept of "blocks" that are combined together to create a geometric model. Much like using Lego? blocks, you can join together individual Seep3D blocks to build meaningful geotechnical structures. To create a model of your geometry, you simply drag a block from the Region catalog window onto your 3D View; then, drop new regions onto the existing region faces to build your model geometry (called the "domain"). The finite element mesh pattern is inherent to each region in the domain. Therefore, as you connect regions together, the mesh gets built automatically, ensuring complete mesh compatibility between regions. This makes it possible to create a 3-dimensional mesh over any domain that you can build with regions.

Materials and boundary conditions are created separately from the domain. This lets you delete regions from the domain without losing any boundary condition or material information. Creating one boundary condition and then applying it to many locations on the domain allows you to only enter the information once, reducing the likelihood of errors. You can also change material properties globally by editing a material; the new values will be used for all regions that use that material.

Once you have setup your domain and applied boundary conditions and material properties, the problem is ready to be analyzed using one of Seep3D’s built-in analysis algorithms. Seep3D contains iterative solvers that can handle linear, nonlinear, steady-state, transient, and adaptive analyses.

Viewing the Analysis Results
You can quickly find the results you need from the massive amounts of data produced by a 3D analysis. For example, you can extract data using “result planes” that “cut” through the domain, displaying surface contours, flow vectors, and flow lines. You can contour any parameter on the exterior hull of the domain, create x-y plots, and copy data into Excel for further analysis.

Intuitive Interface
Seep3D’s intuitive interface gives you quick access to commands. Simply right-click on any object in the 3D view or tree view to modify its properties or execute one of its commands. You can explore your model in 3D by interactively zooming, panning, and rotating within the 3D view. Multiple 3D views can also be displayed. When you modify an object in one of the views, its display is updated within all views.
