Complex domain functions in COMSOL 4.0a

Hi everyone,

I have a parameter in my global definitions expressed using asin function that is implemented in COMSOL. Unfortunately I need to extend the output to complex domain and the implemented asin function does only work in real domain. It worked in complex domain in COMSOL 3.5a:( I tried to define my own analytic function, because asin(x)=-i*log(i*x+sqrt(1+x^2)). Using 'may produce complex arguments' option I successfully plotted real and imaginary part of it. The thing is that the new analytic function does not seem to work in parameters section.

So I have two questions.

1. Is there a way to activate complex domains for COMSOL implemented functions?
2. Is there any way of using your own defined functions in parameter section of Global definitions?

Thanks a lot for any help.
