TypeError: ContactProblem argument mismatch — ‘incompatible function arguments’ in dolfinx_contact

[Dila-Kandel]

Hi all,

I am trying to run a hertz_contact/demo_hertzian_contact.py
using the ContactProblem class from dolfinx_contact. However, I keep getting a TypeError related to argument mismatch, even though my argument types look correct.

Here is the relevant part of my code:

search_mode = [ContactMode.ClosestPoint, ContactMode.ClosestPoint]
contact_problem = ContactProblem(
    [facet_marker], surfaces, contact_pairs, mesh, 
    args.q_degree, search_mode
)

Thank you,
Dila

I have also encountered similar problems.

meshties = MeshTie([facet_marker._cpp_object], surfaces, contact_pairs, mesh._cpp_object, quadrature_degree=5)

TypeError: init(): incompatible function arguments. The following argument types are supported:
1. init(self, markers: collections.abc.Sequence[dolfinx::mesh::MeshTags], surfaces: dolfinx::graph::AdjacencyList, contact_pairs: collections.abc.Sequence[collections.abc.Sequence[int]], V: dolfinx::mesh::Mesh, quadrature_degree: int = 3) -> None

Invoked with types: dolfinx_contact.cpp.MeshTie, list, dolfinx.cpp.graph.AdjacencyList_int32, list, dolfinx.cpp.mesh.Mesh_float64, kwargs = { quadrature_degree: int }

Hi kun-huang,

Have you resolved the error we have been experiencing?

[jorgensd]

This probably depends on how you installed dolfinx and then how you added Asimov contact on top of it. Without those instructions I can’t really help you further.

The reason for this error may be that the version of the nanobind is too high. When I reinstalled the nanobind with version 2.0.0, the error was resolved.
