Restricting a plot to a domain or boundary without a separata data set?

Hello,
I have a parametric solution set. I have created a 2D plot group, where each sub-plot of this group is using the parent plot group's data set. This allows me to switch all plots to different parameter values with one click.
Now, I would like to add another plot to this group, which is restricted only to a boundary. As far as I know I can do this by creating a data set, and adding a selection to it, and then use this data set in that particular plot. The problem with this approach is that this plot is NOT using its parent group's dataset, but its own data set, and I need to change parameter values at two different nodes. This is a guarantee for messing it up at some point, and show an inconsistent plot, some parts of it showing the results belonging to one parameter, and some other parts of it showing the results of another parameter.
Can this be done in a more consistent way?
Thank you
Daniel

Hi,
You can add a Filter subnode to the boundary plot and use that filter to restrict the plot to a single boundary using a logical expression such as
dom==3
which restricts the boundary plot to boundary 3 only. This approach works similarly for domains. You can use a more complex logical expression to include another boundary, for example.
Best regards,

Hello,
Thanks a lot, that's great!
A question for a more complicated case: in my geometry, there is the following structure:
If (param<0.5)
Circle (contribute to a named selection 'MySel')
Else
Polygon (contribute to a named selection 'MySel')
Else
That is, depending on the value of 'param', I have either a circle or a polygon. They contribute (either one or the other) the the same selection, so elsewhere in the model I can refer to this variable boundary by name. I can not refer to it by numbers, since boundary numbering changes between the two cases.
I want to restrict my plot to this named boundary. How can this be done?
Thank y ou
