Representation of two variables in a plot

Good morning,
I have a piece of soil above a water table at depth equal to z = -3.3m.
In order to don't have any problem regarding the water pressure limit at water level, I decide to split the domain in two interval:
interval 1: from z=0 (reference for the water table in COMSOL) to z=0.5m interval 2: from z=0.5m to z=3.3m
I have two different Richards' equations with two different pressures (pl1 and pl2). I set the upper limit for pl2 max = 0kPa at groundlevel.
How can I plot the water pressure distribution of entire domain (pl1 + pl2) with respect to the depth [m] in a unique graph?

Hello Edoardo,
You could create a variable pl3 defined as pl1 in domain 1 and as pl2 in domain 2. You will then be able to plot pl3 in both domains. See the attached toy model for an example.
Best,
Jeff

Thanks Jeff. But in order to have continuity in the water pressure between the two intervals how can I do?
Because I put a precipitation at Ground level that in someway influences the interval related to the waterlevel; but I have the default setting about "NO FLOW" in the intersection that linked the two intervals and I don't know how to replace this condition.

Hi Edoardo,
That's a totally unrelated question so I would recommend you start a separate Discussion Forum thread about it. My background being in a different field, I do not know the answer to this latest query.
Best,
Jeff
