Tutorial 1 - Water uptake experiment教程1 -水吸收实验This tutorial explains how to set up a simple 1D absorption experiment starting from a default project template. In this example a vertical 1D structure is modeled that takes up moisture from the bottom. This tutorial covers the basic steps necessary to set up a coupled heat and moisture transport simulation with CHAMPS-BES.这篇教程解释了如何从一个默认的项目模板设置一个简单的一维吸收实验。在这个例子中垂直一维结构建模,从底部吸收水分。本教程涵盖了利用CHAMPS-BES建立一个耦合的热量和水分运输模拟的基本的必要步骤。Creating the project创建项目Start the CHAMPS-BES user interface. Initially all that is displayed is the main menu and toolbar at the top of the screen. 启动CHAMPS-BES用户界面。最初都是主菜单和工具栏显示在屏幕的顶部。Create a new project using the command: File-New. The New Project Dialog is shown. 使用命令创建一个新项目:文件- 新新项目对话框显示。Select the default project template (the first), enter a filename (e.g. absorption.dpj), select a project directory and confirm the dialog. Now the user interface shows several views of your empty project. The user may rearrange the views later and adjust the screen layout at will.选择默认的项目模板(第一个),输入一个文件名(例如absorption.dpj),选择一个项目目录并确认对话框。现在用户界面展示了几个空项目的观点。用户可以重新排列视图后,调整屏幕布局。Setting up the grid设置网格Open the context-menu of the construction view (right-click on the empty construction grid) and select Setup construction grid The Setup new grid dialog is opened. Leave everything like it is and confirm the dialog. This creates a structure with one material layer. Execute the Change width/height. command to open the element geometry edit dialog打开右键菜单的结构视图(右键单击空结构网格)并选择设置结构网格设置，新的网格对话框打开。其他都不要管，确认对话框。这将创建一个结构和一个材料层。执行改变宽度/高度命令打开元素几何编辑对话框Import and assign material引进和分配材料Now move over to the materials view and execute the New. (material) command (either via context-menu or button). In the Material Import Dialog select a material file such as the Brick Wienerberger, select the radio button Import material data into project and confirm the dialog. 现在搬到资料查看和执行新(材料)命令(通过右键菜单或按钮)。材料导入对话框中选择一个材料文件如砖股票,选择单选按钮的材料数据导入到项目并确认对话框。Depending on your needs the user may want to create a link to the material file instead (refer to the Material Import Dialog documentation for available options).根据您的需要,用户可能想要创建一个链接文件材料(参考材料导入对话框文档可用选项)。After importing the material it will show up in the materials list view. In order to assign a material the user first has to select the appropriate cells in the construction view and then use the Assign material command, by pressing the green assignment button in the toolbar: 导入材料之后,它将出现在材料列表视图。为了分配材料用户首先必须选择适当的细胞结构视图,然后使用命令分配材料,按下绿色的任务按钮在工具栏:Since the only material layer in the grid is already selected, the user can simply execute the Assign material command and the material will be assigned to the grid. The user can now also see an assignment entry in the assignment view.由于唯一的材料层网格已经被选中,用户可以简单地执行指定命令和材料将被分配到网格。用户现在也可以在任务视图中看到一个任务条目。Hint: To assign something to the construction grid there is a context-menu.提示:分配结构网格有一个右键菜单。Define and assign initial conditions定义和分配初始条件For a coupled heat and moisture simulation the user will need an initial condition for the energy balance and one for the moisture balance. For this example well create temperature and relative humidity initial conditions. Select the Initial condition tab in the conditions view 对于热湿耦合模拟，用户将需要一个能量平衡的初始条件和水分平衡的初始条件。在这个例子中,我们将创建温度和相对湿度的初始条件。选择“初始条件”选项卡视图的条件and execute the New. command (from context menu or using the toolbar button). In the Initial Condition Edit Dialog type Initial temperature as identification name, specify 20C and confirm the dialog. Then create another initial condition, select Relative Humidity as type, name it Initial RH and set it to 5 % relative humidity.并执行新命令(从上下文菜单或使用工具栏按钮)。在初始条件编辑对话框类型“初始温度”作为识别名称,指定20C和确认对话框。然后创建另一个初始条件,选择的“相对湿度”类型,命名为“初始RH”,将其设置为5%相对湿度。Now mark both initial conditions and execute the Assign Conditions command (the green button with the arrow again). They will be assigned to the currently selected material layer (actually the only grid element that can be selected in the construction grid right now). 现在标记初始条件和执行分配条件命令再次与箭头(绿色按钮)。他们将被分配到当前选择的材料层(实际上是现在 在结构网格中唯一可以选择的网格元素)。Hint: If accidentally something was done that the user didnt want to do, simply use the UNDO button to reverse the change. 提示:如果不小心做了一些用户不想做,简单地使用撤销按钮来扭转这一变化。Define and assign boundary conditions定义和分配边界条件For a very simple model of an absorption experiment, we simply assign a water contact boundary condition. Select the Boundary condition tab in the conditions view and create a new boundary condition (command New. again). In the Boundary Condition Edit Dialog the user needs to specify several things. Set the identification name to bottom water contact. Set the type to Water contact and leave the kind as Surface value. For this boundary condition the user also needs to assign a Water content climate condition. Click on the Create new. button in the Water content line to open the Climate Condition Edit Dialog. Name the climate condition water contact and specify a constant moisture content. For an absorption experiment the user wants to specify the final equilibrium moisture content after the absorption experiment. For the Brick Wienerberger that will be 0.319 m3/m3 (use the CHAMPS-BES Material Inspector to check material properties). Confirm the climate condition dialog to get back to the boundary condition dialog. The user will now see that the newly created climate condition is assigned as source for Water content data. Similarly create and assign a climate condition for the water temperature (name it water temperature or something like this).对于一个非常简单的吸收实验模型,我们只是分配一个水接触边界条件。在条件视图中选择“边界条件”和创建一个新的边界条件(命令新再一次)。边界条件编辑对话框中用户需要指定几件事情。识别名称设置为“底水接触”。类型设置为“水接触”,保留类型为“表面值”。这种边界条件的用户还需要分配一个“水分”气候条件。在“水分”行点击“创建新”按钮打开气候条件编辑对话框。命名气候条件为“水接触”并指定一个恒定的含水率。对于一个吸收实验用户想要指定吸收实验后最终的平衡含水率。“砖股票”,0.319立方米/立方米(使用CHAMPS-BES材料检查员检查材料属性)。证实了气候条件对话框回到边界条件对话框。用户将看到新创建的气候条件分配作为“水分”数据的来源。类似的，气候条件的创建和分配一个水温(名称“水温”或类似)。Hint: After completing the tutorial, try varying the water temperature and see how the moisture and temperature profile is influenced when different water temperatures are used. 提示:完成本教程之后,尝试不同的水温,看看当使用不同水温，湿度和温度的配置文件是如何受影响。The user can now assign the boundary condition (execute the Assign Conditions command). However, this time the user will be prompted to specify a location for the boundary condition. Select the bottom side only (deselect all others) and confirm the assignment dialog. 用户现在可以指定边界条件(执行分配条件命令)。但是,这一次会提示用户指定边界条件的位置。选择底部一侧只有(取消选择所有其他)并确认任务对话框。Define and assign outputs 定义和分配输出The model is now almost ready for calculation. Still, the user needs to define what kind of outputs the user would like to obtain. The default project template, which was used in this tutorial, already contains output grid and format definitions. All the user has to create are some output files that will contain your outputs. 这个模型现在几乎准备好计算。不过,用户需要定义用户想获得什么样的输出。,本教程是使用默认的项目模板,已经包含输出网格和格式定义。用户必须创建所有都会是将包含您的输出的一些输出文件。Hint: Read the section Output overview to get a better understanding of how the output system of CHAMPS-BES works. 提示:阅读输出概述部分以更好的理解CHAMPS-BES的输出系统是如何工作的。The user can create new output files in the outputs view. These output files define how the outputs are done (via an output format), when outputs are done (by using a specific output grid) and into which file the data is written. Later one assigns them to the grid and defines where they are done (or where the data for the outputs is taken from). First create a temperature field output (with command New. ).在输出视图中用户可以创建新的输出文件。这些输出文件定义输出是如何完成(通过一个输出格式),当输出完成(通过使用一个特定的输出网格)及数据写进哪个文件中。后来一个分配到网格和定义它们完成的地方(或输出的数据取自)。首先创建一个温度场输出(命令新)。Select the Temperature output format and select the default output grid. The filename temp_field.out is automatically given. Confirm the dialog and create another output file with Moisture mass as output format. Finally we want an output file with the total water mass in the structure, so create an output file with Water mass integral as output format.选择“温度”输出格式和默认的输出网格。“temp_field”文件名自动生成。确认对话框和创建“水分质量”的另一个输出文件的输出格式。最后,我们想要一个结构总水量的输出文件,因此创建一个“水质量积分”输出文件的输出格式。Finally these output files need to be assigned (the simulation will still run without them, but one wouldnt get any results). Select all three output files and assign them (Assign Output Definition command).最后这些输出文件需要分配(没有它们模拟仍将运行,但不会得到任何结果)。选择所有三个输出文件并分配(分配输出定义命令)。Discretization of the structure结构的离散化After everything has been assigned the structure still needs to be discretized. In the context menu of the construction grid select Discretize-Discretize selected rows. to open the Discretization Dialog. For this example we use equidistant spacing, but feel free to try out the variable discretization option. Change the number of elements to 100 or so (more then 50 will usually give very smooth absorption profiles) and confirm the dialog. The discretization is then shown in the construction form. If one doesnt like the result use UNDO and try again.一切都被分配后结构仍然需要离散。在结构网格的上下文菜单中选择离散化- 离散化选择的行打开离散化对话框。在这个例子中,我们使用等距间隔,但随意尝试变量离散化的选择。元素的数量更改为100左右(超过50通常会给非常顺利吸收概要文件)并确认对话框。然后离散化就以结构表格形式显示。如果不喜欢这个结果就使用撤销键并再试一次。Simulat
