HYDRUS 2.x Tutorial 5.15: Multiple Intersection of Surfaces

This project has no physical meaning and we present it here only as an example of a complex object with multiple Intersections of Surfaces. In the cylindrical domain we have a system of cylindrical tubes that penetrate each other. It was possible to create the entire domain, including Intersections of Surfaces, in HYDRUS (without the help of other CAD programs) within few minutes.

	Domain Geometry - Figure 1 The whole domain is displayed in this figure in the transparent mode. Inside of the domain you can see the system of vertical pipes. In this case the tubes are defined as holes, but could equally well be filled by various materials. Hint: Click on a figure to enlarge it.
	Domain Geometry - Figure 2 This figure highlights the internal pipes, resulting after cutting out intersections with a horizontal hole.
	FE-Mesh - Figure 1 The generated FE mesh. The number of 3D elements is around 200,000.
	FE-Mesh - Figure 2 Another view of the FE mesh. Refinement of the FE mesh around a circular hole is clearly visible.
	FE-Mesh - Figure 3 A cross-section through the FE mesh. HYDRUS allows to view any cross-sections of the FE mesh and to form from them named groups of elements (the FE-mesh Sections). The FE-mesh Sections are very useful for either specifying properties directly on FE mesh (as an alternative to specifying properties on the geometric objects) or when displaying results.
	Graphical Display of Results Figure shows pressure heads at selected interior surfaces of the transport domain. Figure demonstrates the use of FE-mesh Sections (discussed above) for displaying the results or other quantities anywhere within the computational domain. The Color Smoothing option is used here. Colors and scale are fully customizable according to user requirements. HYDRUS offers numerous ways to display the results.
