Time and space dependent boundary conditions

[Patco96]

Hi! I am using deepxde with the navier stokes equations but I have not been able to set the boundary conditions properly.

I am considering 40 observation points and 100 measurements for each. Up to now, I have been setting the boundary conditions as a list of PointSetBC for each component (2 components). This leads to a really long list of boundary conditions.

Is there a better way to implement this?

I don't quite understand your question. Each variable has a BC, and thus the number BCs is equal to the number of variables. A PointSetBC can have a set of points, not a single point.

Thank you! Even though you didn't understand the question, you answer was enough to do it 😄

When trying to use PintSetBC I was passing both variables together and thought only one set of points could be passed at a time. Knowing that the number of BCs is equal to the number of variables was the key.

Thanks again!
