How to realize moving boundary integration in COMSOL?

Please login with a confirmed email address before reporting spam

This is a math problem in calculating the photo-ionization of streamer discharge by comsol.
The 1-d calculation domain is (0,d), and one point inside this domain is x.
We need do the calculation in two steps:

1, Integration1(0,x) . 2,To change x value between 0 and d, and do this integration for every point inside the domain.
THis is easy to be realized in matlab by
for(0<x<d)
integration1(0,x)
sum(x)=integration1
end

Anyone can give some suggestions, many thanks.
