Good morning, I was wondering about how to set a boundary condition just in one point of the boundary (this e.g. is needed for the Laplace problem with Neumann b.c.). In particular, is this command correct? Gamma = mesh.locate_entities_boundary(domain, dim=1, marker=lambda x: np.logical_and.reduc…

The dimension should be zero (not 1), as you are restricting a vertex not an edge.
