<\/span>Creating a new model<\/span><\/h2>\n\n\n\n

You can start a new model from the main screen after starting Reves DSE by clicking the New button<\/strong> \"\" , the \"\" Create a new model button <\/strong>or via the menu bar File, New<\/strong>.<\/p>\n\n\n\n

<\/span>Creating a basic model<\/span><\/h2>\n\n\n\n

You can create a basic model by adding expressions, procedures and\/or other items to the model canvas ( Adding new items to the model<\/a> ). If you want to bring a certain structure to your model, you can group items in modules ( Using modules<\/a> ) and connect them with connectors ( Connecting modules on the canvas<\/a> ). If you are content with your model and there are no errors, you can select an existing view design or make a new one ( Creating a view<\/a> ) to use as your solution output interface. By running a view you can create an empty solution set ( Starting a view<\/a> ) and start a calculation ( Generating solutions<\/a> ).<\/p>\n\n\n\n

<\/span>Opening a model<\/span><\/h2>\n\n\n\n

You can open an existing model from the main screen after starting Reves DSE by clicking<\/strong> the Open button<\/strong> \"\" , the \"A Open a model or model button<\/strong>  or via the menu bar File, Open<\/strong>.<\/p>\n\n\n\n

A recent file list is available on the main screen. From there you can open your most recently used models and projects. You have the option to directly open a model file in either knowledge edit mode<\/em> (\"\"), or calculation mode<\/em><\/a> (\"\"), by clicking the respective icon for the file.<\/p>\n\n\n\n

Reves DSE uses two types of files, models<\/em> and projects<\/em> to organize the knowledge, views and results. A Reves DSE Model<\/em> file (.mrpx<\/em>) contains all the knowledge to perform calculations and the views<\/a> to provide input and show calculation results; a Reves DSE Project<\/em> file (.mrpr<\/em>) contains just the calculations. You can start new calculations in a model, but you cannot edit the knowledge in a project.<\/p>\n<\/div>\n<\/div>\n\n\n\n

You can also open a model or project directly from disk, without first starting Reves DSE, by double-clicking the file name in Windows Explorer. By default, double-clicking a model file, will open a copy of the model in calculation mode. To open it in knowledge edit mode, right-click the file and select Edit<\/strong> from the shortcut menu.<\/p>\n\n\n\n

If a model contains an error, or if there are no views at all, Reves DSE will not be able to start a new calculation directly. If this happens, Reves DSE  will let you know that starting a calculation is not possible and will ask you if you would like to open the model in knowledge edit mode instead. If only some views contain errors, Reves DSE will start in calculation mode using the valid view.<\/p>\n<\/div>\n<\/div>\n\n\n\n

<\/span>Saving a model<\/span><\/h2>\n\n\n\n

You can save the model you are working on by clicking the Save button<\/strong> \"\" or via the menu bar File, Save<\/strong> or File, Save As<\/strong>.<\/p>\n\n\n\n

<\/span>Using the toolbox<\/span><\/h2>\n\n\n\n

In the toolbox you can find the items you can use to build (\u201cModel\u201d) or illustrate (\u201cView\u201d) your model. See Adding new items to the canvas<\/a> on how you can add items from the toolbox to the canvas.<\/p>\n\n\n\n

<\/span>Using the canvas<\/span><\/h2>\n\n\n\n

You can manipulate the canvas in the following ways:<\/p>\n\n\n\n
