Hi,

how we define mesh of an interval [a,b] with FreeFem++?

Thank’s in advance

Hi,

how we define mesh of an interval [a,b] with FreeFem++?

Thank’s in advance

Just some additional remarks:

```
load "msh3"
int n = 50;
real a = 5;
real b = 15;
meshL Th = Sline(n, [a + (1+1.0/(n-1)) * (b-a) * x, 0, 0]);
for (int i = 0; i < Th.nt; i++)
{
cout << i << " " << Th[i][0].x << endl;
}
```

Sline seems to leave out the last point, so b is not included. Probably so that several 'Slines ’ can be linked together by simple addition. Sline does not provide a unit interval.

Thus I found that some scaling is required.

Also make sure that you use version 4.7.-1.

Kind regards

Gerald
