Hi everyone, I’m new here, and I need some help.
I’m working on CSI (contrast source inversion method) which is an inverse scattering problem. In this method, I have to solve EDP this is why I use Freefem++. My domain is divided into 3 parts, I solve my problem in all the domain (Omega) but then I have to select my solution in only 1 part of the all domain, how can I do that in freefem ?
Thank u.
you can control the domain by specifying it.
eg. for a domain containing x = 1then
(x<1)* expression + (x>=1)*someotherexpre
it can define the two domains, first with less than 1 and other with greater than equal to a domain.
