I have used (r, theta, phi) as the parameters in PDE.

And my boundary condition is f(r=1) = 1.

I have set the periodic boundary conditions in configure the net arch by `periodicity={"y": (0,2*np.pi), "z": (0,np.pi)},`

.

However, I don’t know how to configure the boundary condition at `r=1`

.

Currently I use the following method, but it seems don’t work.

```
bc = PointwiseInteriorConstraint(
nodes=nodes,
geometry=geo,
outvar={"u":1/(24 * x)},
batch_size=cfg.batch_size.boundary,
bounds={x: (0.99999, 1), y: (0, 2*np.pi), z: (0, np.pi)},
)
```
