I just updated dolfinx and multiphenicsx today and it seems multiphenicsx.fem.DofMapRestriction no longer works for me as it used to. I use the same construction as in the Lagrange multiplier interface tutorial. In fact, I get the same error running the above tutorial on my installation (I ommitted …

[image] hermanmak: It seems the fact that I used different compilers to install dolfinx and multiphenicsx Oh yeah, that is risky business, especially when wrapping with pybind11 or nanobind :wink:

Which version of dolfinx are you using? Since you installed via spack, it’s probably to the development version. Please double check that you are using a compatible multiphenicsx version, see Installation — multiphenicsx The errors is complaining about a list vs np.array, which is one of the change…

As you mentioned I installed via spack with dolfinx@main. I followed the instructions here for the development version of multiphenicsx. I even tried explicitly making the second input into a list as multiphenicsx.fem.DofMapRestriction(V1.dofmap, list(dofs_V1_Omega1)) which gave the same error excep…

Hello, I’m currently facing the same problem with multiphenicsx.fem.DofMapRestriction on the hpc running the tutorial in spack enviroment but it works with my computer using docker environment. The error is as follows: Traceback (most recent call last): File "/data/horse/ws/jesa624b-Multiphenics…

Hello, I also have the problem using dolfinx@0.9.0. I installed dolfinx on the HPC via spack and used the GCC/13.2.0 compiler. Using the installation commands specified here also works - no error messages occur. However, when running tutorial 3 (interphase problem), I got the same error as stated …

In case you did not notice, this issue was discussed in another thread . While the problem was eventually fixed, the installation followed there is through conda. Perhaps you can adapt it to the installation process you are following.

Thank you for your answer! I installed nanobind==2.1.0 via pip in spack after the installation of dolfinx@0.9.0. The compiler I am using are specified in the compilers.yaml file: compilers: - compiler: spec: gcc@=13.2.0 paths: cc: /software/rapids/r24.04/GCCcore/13.2.0/bin/gcc …

It will definitely use the C++ compiler. The point is that both the compiler and the nanobind version must match exactly the ones that were used to build dolfinx.
