Solving problem sequentially

I want to use a solution of a static problem(emqa1) for a time-dependent problem(emqa2).


I defined two modes. (emqa1, emqa2)

I put some of expressions into expression-subdomain tab. These expressions are dependent only on solution of

first mode(emqa1), and should not change while solving a second mode(emqa2).

For example, I put a expression named 'theta' which has a expression of 'atan2(Hy_emqa1/Hx_emqa1)' into the expression-subdomain tab.


And using this values in a subdomain, I want to solve time-dependent problem(emqa2).

But I am worrying that COMSOL removes this values while solving 'emqa2' resulting in wrong solution.

While solving (emqa2), does COMSOL try to calculate the expression like 'atan2(Hy_emqa1/Hx_emqa1)'

again or not?
