Plot while solving is a technique used to briefly interrupt the simulation and launch some predefined plot commands and then continue with the simulation. Both normal plots and graphs can be plotted for probes during the simulation.
The probes automatically create a Probe Table node for displaying numerical results in the
Table window and an associated plot group with a
Probe Table Plot node that plots the probe data as a line graph in a separate
Probe Plot window. For further processing, the probes also add datasets such as
Domain Point Probe datasets (
), which give access to the probe data. For further control, specify the table and plot window each probe uses.
When the simulation has finished, click the Update Results button (
) in the probe
Settings window (or in the
Definitions toolbar) to change the settings for a probe and update the results information using the last solution in the model. Then right-click the
Definitions node (or the
Probes node if the
Definitions nodes are grouped by type) and select
Update Probes.
After an update, all the probes are available as Derived Values nodes under
Results. These values can be modified and reevaluated in standard ways. Note, however, that if the changes you do to probes under
Results are in conflict with the probe settings then those changes will be overwritten by the probes next time you update them.
) monitor the development of a scalar-valued quantity (real or complex-valued number) from a time-dependent, frequency-domain, or parametric simulation by two different results presentations: tabulated data and 1D graph plots. You can probe while solving, as a monitor and diagnostic tool, and probe after the computation is finished for results analysis. On top of this functionality, a probe variable in the model component’s namespace and with a global evaluation scope is also defined. The probe variable’s name appears in the Probe variable field. You can use this variable as any other variable in, for example, equations, boundary conditions, or a stop condition, as well as for global evaluations.
