This article describes what needs to be done if you want to create an application that uses the OpenDAModelProvider interface of deltashell to work with DS models. I created a windows forms application using the 'zip' file from the nightly build. Use at least revision 12906 (this is the revision I used). There was a bug in earlier build

Setup

1 Create a folder called D:\ODA
2 Download deltashell.zip and extract it to D:\ODA\shell. Now you should have a folder D:\ODA\shell\plugins and D:\ODA\shell\release

Creating the application

3 Create a windows forms application called 'Runner' in D:\ODA\Runner
3.1 Add references to the following assemblies :

from D:\ODA\shell\plugins\DeltaShell.Plugins.OpenDA
DeltaShell.Plugins.OpenDA
OpenDA.DotNet.AdditionalInterfaces

from D:\ODA\shell\release
OpenMI.Standard2
DelftTools.Shell.Core
DelftTools.Units
DelftTools.Utils
DeltaShell.Core

So your references look like this

Add a button to the form and add the following code to click event handler:

                var provider = new DeltaShell.Plugins.OpenDA.DeltaShellOpenDAModelProvider();
                provider.Initialize(@"D:\ODA", "settings.xml");
                var instance = provider.CreateInstance();
                provider.SaveInstance(instance);

Creating the model.

1 Start the loader in D:\ODA\shell\release\DeltaShell.Loader.exe. Do not use a different version of DS to create the model. You might get versioning problems with the file
2 Add a demo flow model via menu development->'flow model 1d (demo network)'.
3 Rename the model to 'model'.
4 Save the project as model.dsproj in d:\ODA and close DeltaShell

The settings file

Create a text file named settings.xml in D:\ODA. These are the contents:

<?xml version="1.0"?>
<DeltaShellOpenDAModelProviderSettings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <ProjectPath>D:\ODA\model.dsproj</ProjectPath>
  <FullyQualifiedModelWrapperType>DeltaShell.Plugins.DelftModels.WaterFlowModel.OpenMI2.OpenMI2WaterFlow1DWrapper, DeltaShell.Plugins.DelftModels.WaterFlowModel, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null</FullyQualifiedModelWrapperType>
  <ModelName>model</ModelName>
  <DeltaShellLoaderFolder>D:\ODA\shell\release</DeltaShellLoaderFolder>
</DeltaShellOpenDAModelProviderSettings>

Running it.

Start the runner application and click the button. If all goes well your model.dsproj project will contain a model called Calibrated model. This is the model that was passed in to the SaveInstance method of the provider.
