Values of variables not solved for: ...

Hi all!

I have two physics, both of them are time-dependet study.
My question: If I want to couple these two physics together , there are two options:

Values of variables not solved for: Time(s)

"Automatic"
"All"

what is the difference between these two option?

I also attached snapshot of my screen to explain better my question

There are three options: 1) "Automatic" 2) "All" 3) "Interpolated"

What is the difference between them? Is there any tutorial or is there any explanation of this section in comsol manual?

Please let me know. Hope to hear from you

Ok, Now I found what is the difference. If you go to the COMSOL reference manual page 901, there is the explanation, I attached here the screenshot of this section as "Q2".

But I cannot understand the two sections:
1) what is the difference between choosing: "Automatic" and "Last" ?? Select "Automatic" (the default) to use the solution for the last time.
Select "Last" to use the last solution

2) What does this sentence mean? Is there anybody explain it more in detail? "When you select "All", an interpolation done internally for time-dependent simulations".

Thanks in advance for sharing your information.
