Would be great to improve the situation with technical means, but I don't have the time to work on this at the moment. But I will reopen this issue and...

> How many different fields would we want to support? Something like `def initialize(self, coupling_subdomain, mesh, read_function, read_function2, write_function, write_function2, dimension=2):` where we support a fixed amount of fields (here...

I'm just providing a brief update on this from my current perspective today, because I just received a request by a user and I think it's useful to summarize this...

Added the "student" label, because I think it might be a nice thesis topic to actually create a 3D tutorial + extend the adapter correspondingly.

Here is a rough plan on how someone could start working on this issue: * Comment out the assertions that enforce 2D and see where problems pop up. [`SegregatedRBFInterpolationExpression`](https://github.com/precice/fenics-adapter/blob/8a21819bd5c567854e809acfadcd1e75bf539640/fenicsprecice/expression_core.py#L163), for...

I investigated this issue a bit. Main problem with FEniCS is that it does not provide the `VertexOnlyMesh` needed for this purpose. We could try adapting the [`firedrake` version of...

I tried to create a mesh myself. I will provide the example code below. Note that the example is not working. I guess it is just not that simple to...

Neither ``` editor.open(mesh, type="point", tdim=tdim, gdim=gdim) ``` nor ``` editor.open(mesh, type="vertex", tdim=tdim, gdim=gdim) ``` work. Looking at the ufl package it looks like [`vertex` is the correct type](https://bitbucket.org/fenics-project/ufl/src/a6e889ca592d5dd2304ceb6afb82d09e3569968c/ufl/cell.py#lines-96:101). However, the...

> UFL should support vertex cells - at least I added such support to the [github hosted FEniCS/ufl](https://github.com/FEniCS/ufl/) repository which I believe is the current UFL core and appears to...

I asked a question about this issue in the FEniCS discourse forum (https://fenicsproject.discourse.group/t/unclear-how-to-use-mesheditor-with-pointcloud/5660). @ReubenHill Thanks for the explanation!
