Building an Expression Using Existing Quantities

When you are entering an expression for a new output variable, you can insert part or all of the expression using the options in the Calculation and Function sections of the Output Variables window.

To add an input variable by inserting part or all of the expression:

  1. Click Maxwell 3D, Maxwell 2D, or RMxprt and then select Results > Output Variables or, in the Project Tree, right-click on Results and select Output Variables from the short-cut menu, or on the Modify Report dialog box, click the Output Variables button.
  2. The Output Variables window appears.

  3. In the Output Variables section, enter a name for the new variable in the Name box.
  4. To insert a quantity:
    1. From the Report Type drop-down menu, select the type of report from which you want to select the quantity.
    2. From the Solution drop-down menu, select the solution from which you want to select the quantity.
    3. From the Category list, select the type of quantity you want to enter.
    4. From the Quantity list, select the quantity or the geometry.
    5. From the Function list, select a ready-made function (this option is the same as inserting the function from the Function section).
    6. If applicable, from the Domain list, select the solution domain.
    7. Click Insert Into Expression.

    The selected quantity is entered into the Expression area of the Output Variables section.

  5. To insert a function:
    1. In the Function section, select a ready-made function from the drop-down menu.
    2. Click Insert Function into Expression.

    The function appears in the Expression area of the Output Variables section.

  6. When you are finished defining the variable in the Expression area, click Add to add the new variable to the list.
  7. Repeat steps 2 through 5 to add additional variables.
  8. When you are finished adding output variables, click Done to close the Output Variables window.
Note: Remember the evaluated value of an expression is always interpreted as in SI units. However, when a quantity is plotted in a report, you have the option to plot values in units other than SI.
