Computing the Initial Values
In some situations you might want to evaluate and plot values, expressions, or functions that need not be solved for, such as initial values and functions evaluated using the initial values.
To make the initial values available for results evaluation and plotting, right-click the Study node (), and select Get Initial Value (). By default this plots the initial values of the variables solved for as specified by the Field subnode () under a Dependent Variables node for the first study step in the solver configuration. For a parametric sweep, it uses the first parameter value.
For each study step you can also right-click and choose Get Initial Value for Step ) to evaluate the initial value for that step. It is also possible to get the initial value for a particular solution under Solver Configurations by right-clicking a Solution node and selecting Solution>Get Initial Value ().
Also variables not solved for (such as a solution from a previous time-dependent or parametric analysis) can be made available for results evaluation and visualization. Select Values of variables not solved for from the Keep solution list under Output in the Dependent Variables node.
