Hello,

I am importing my meshed geometry from GMSH to FreeFEM along with the labels. I want to implement the following I.C. using labels. I tried using implicit function approach but it doesn’t work.

U = {1.0 at inlet i.e. x==-3 and 0 otherwise.} (Required Initial condition)

```
func ic = (x==-3); // if at inlet then returns 1 otherwise 0.
Vh u = ic;
```
