Coupling nodes along a face or a edge to a master node

1

HI,
I wanted to couple the nodes of a face or the edge to a single master node similar to the coupling command in Ansys. Is there a way to do so in fenics?

If you want to constrain the nodes then I would recommend checking out dolfinx and its extension dolfinx_mpc by @dokken : GitHub - jorgensd/dolfinx_mpc: Extension for dolfinx to handle multi-point constraints.

I don’t think there is a good way to do that in legacy dolfin.

Hi,

Is there a way to achieve a voltage coupling effect in FEniCS similar to ANSYS tree as attached below:
