Hi, I have someting to know.
As you know, the initial condition set is as follows:
initial Values of Variables Solved For
Method: initial expression, Solution
Solution: Zero, Solver1, Solver2
in magnetic problem solving,
I made study1 for low frequency, and study2 for high frequency for the better convergence.
So I'd like to solve at first study1 and after that study2 by using initial condition from study1.
How do I set the initial values?
in study2
initial Values of Variables Solved For
Method:Solution
Solution: Solver1
is it right?
What's the difference between initial expression and Solution in Method set?
and when can i use Zero for Solution?
In addition, I changed Solution to Solver2(from Solver1), and I got the very diffenrent calculation result.
Could you explain the reason?
Thank you in advance.

Hi
I would say read carefully through the dynamic help on:
"Specifying Values of Dependent Variables"
And you should get the responses

Good luck

Dear Ivar,
I could not find the "dynamic help" that you are addressing!!! Where is it? :) I searched through all comsol documents but I could not find even one example in that they have used this option. :(
I would appreciate it if you could answer this question of mine.
I am obtaining neff of a waveguide at different frequencies say 10 or 20 frequencies (dispersion graph) . I need to pass one neff from one iteration to the next as an initial value. I obtain results and they seem correct but I am not sure of my implementation.
In Mode Analysis node, I check "initial values of variables solved for", then
method: solution
study: zero solution
then I use parametric sweep.
Is my implementation correct? If not, what should I do?
Thank you,
Roya
