Hi,

Let’s take the official elasticity example from here. Let’s remove the body force f and add another boundary condition at the right side (`label = 2`

). This boundary condition is a pressure `p`

that will elongate the beam in `x`

direction.

Is this the right way to assign a pressure boundary condition to the right side? I would say it is not, however, I can’t figure out what is.

```
25 solve lame([u, v], [uu, vv])
26 = int2d(Th)(
27 lambda * div(u, v) * div(uu, vv)
28 + 2.*mu * ( epsilon(u,v)' * epsilon(uu,vv) )
29 )
30 - int1d(Th, 2)(
31 p*uu
32 )
33 + on(4, u=0, v=0)
34 ;
```
