Specifying Dirichlet boundary condition using PointSetBC

[DeepaMahm]

Hi Prof. @lululxvi

I've a 2D geometry created using PointCloud.

geom = dde.geometry.PointCloud(
     points=np.asarray(domain_points),
     boundary_points=np.asarray(lbc_points),
 )

 timedomain = dde.geometry.TimeDomain(0, 60)
 geomtime = dde.geometry.GeometryXTime(geom, timedomain)
 
 # left boundary condition
 lbc_values = [[5] for _ in range(len(lbc_points))]
 lbc_points_time = np.hstack((np.asarray(lbc_points), np.ones((len(lbc_points), 1))))
 lbc = dde.icbc.PointSetBC(points=lbc_points_time, values=lbc_values)  # [0, 1]

When I try to specify the Dirichlet boundary condition using PointSetBC to solve a forward problem, I am unsure how the time needs to be specified.

I referred to this example:
https://deepxde.readthedocs.io/en/latest/demos/pinn_inverse/diffusion.1d.inverse.html

where time is specified to the PointSetBC by appending t=1 to observe_x .

observe_x = np.vstack((np.linspace(-1, 1, num=10), np.full((10), 1))).T
observe_y = dde.icbc.PointSetBC(observe_x, func(observe_x), component=0)

I'm trying something similar by appending np.ones((len(lbc_points). Here lbc_points is a 2d array with the coordinates of points at the left boundary of the geometry.

lbc_points_time = np.hstack((np.asarray(lbc_points), np.ones((len(lbc_points), 1))))

Since DirichletBC holds at all time points specified in TimeDomain(0, 60) ,
I am not sure if one has to choose a time step and specify the BC values explicitly at all the time instances .

Could you please advise on how to proceed?
