How do I export pictures for multiple design points?

Pierre Thieffry

I am running a simulation for which I create figures for various results. I want to export them for each design point. How can I do this?

Here's a sample code to use in a Python Code object. For this to work, you will have to use version 23.1 and above as picture export in batch mode did not work in earlier versions.

Small bonus: you'll see how to retrieve the design point number and the user_files folder without the need for executing a script at project page level.

Hello @Pierre Thieffry ,

thank you for the post, it is really helpful!

I am trying to do some modifications on the legend text, to increase it.

I've tried something like this based on the documentation which I found on the web, but it is not working:

ExtAPI.Graphics.ExportImage(filename,  GraphicsImageExportFormat('png'), GraphicsImageExportSettings.FontMagnification(1.3))

Can you help me please with this ?

Figures in this example mean static generated images and not the dynamic Ansys plots. .AddFigure() will add the figure below any selected result.

I have an adaptation that will generate the image if it doesn't already exist and write that image to file:

    dpn = wbjn.ExecuteCommand(ExtAPI,"returnValue(a+Parameters.GetActiveDesignPoint().Name)",a="DP")
    user_dir = wbjn.ExecuteCommand(ExtAPI,"returnValue(GetUserFilesDirectory())")

    results = ExtAPI.DataModel.GetObjectsByType(DataModelObjectCategory.Result)

    for result in results:
        ExtAPI.Log.WriteMessage('bob')
        children = result.Children
        if not any(i for i in children if 'Figure' in i.ToString()):
            children = result.AddFigure()
        elif 'Figure' in children[0].ToString():
            children = children[0]
        children.Activate()
        filename = os.path.join(user_dir,'Figure - '+children.Parent.Name+'_'+dpn+'.jpg' )
        ExtAPI.Log.WriteMessage(filename)
