questions:

1. why the "export" was not executed?

2.  how to plot an expression from resultsdirectory?

 

what i am trying to achieve is do a DC followed by an AC within each MC run and nested with a sweep of a parameter.

 appreciate any feedbacks.

  • That's because you're trying to sweep the variable from the global variables. As I said before, that is not supported in ADE XL.

    You must do the sweep in a corner for this to work. Expand the corners in the Data View assistant, and click on the "Click to add corner". Add a corner with the "Add New Corner" icon (it's a thermometer with a *). In the Variables section, hit the Click to add, and in the cyclic that appears, pick EQ. In the column for your new column, type 0:1:10 (or click in the field, and then hit the Set Sweep Value icon (the dial icon) - this can also be found in the right mouse button over the field - if you do that you get a form like you get in the Variables part of the Data View assistant to set up the sweep.

    At the bottom of the corner definition, you'll see that the number of corners will reflect the number of points in the sweep within the corner - effectively a corner can have a number of sub-corners.

    You can also set up the models from the corner definition too - although it's not essential. If you don't it will pick the model setup from the test (if my memory is correct).

    Of course, you'll need to disable the sweep from the variables section of the data view assistant.
