Simulate for an additional value of a parameter after completing a parametric sweep

Hello,
I am a new user of Comsol and having difficulties to overcome a simple problem.
I am simulating a semiconductor device with varying gate voltage Vg and drain voltage Vd using the parametric sweep.
Let's assume I have completed a parametric sweep "Study 1/Step 1: stationary" with the following values of the variables: Vg=2 [V] Vd=1 2 3 4 [V]
Comsol saves (names) the data output as Study 1/Solution 1 (sol1).
At this point, if I decide to simulate Vd=5V, what do I need to do?
I do not want to re-simulate the first parametric sweep and I also want to use Vd=4V data as initial values for the Vd=5V simulation.
Do I need to create a new Stationary Study or do I need to add another step under Study 1?
In the very end, can I create a single data file including all the combinations of parametric sweeps together so that I can easily plot graphs of them?
Thanks and regards, Bugra

Dear Bugra,
Yes you can create a new study with a stationary study step, and use the settings under the section "Values of Dependent Variables" to specify the Vd=4V data as the initial condition.
After solving, you can create an empty study, and then add a "Combine Solutions" node to concatenate the two solutions for plotting.
Sincerely,
Chien
