Hello everyone, I noticed that in the fenics-adapter github page, it says " preCICE-adapter for the open source computing platform FEniCS. Note: The adapter **currently only supports 2D simulations in FEniCS**", however in the “get\_fenics\_vertices” function I found :

> if dims == 3:  
> coords.append([v.x(0), v.x(1), v.x(2)])

It seems support 3d case. so I am wondering whether the current version of fenics-adapter support 3d case?

Best regards.  
wenguo.

Hi @zhuwenguo

3D is work in progress. Some missing functionality is added here:

> <https://github.com/precice/fenics-adapter/pull/133>

> This PR adds 3D case handling capability to the adapter. Currently only 3D FSI s…erial cases are tested. The testing is done here: https://github.com/precice/tutorials/pull/222. Closes https://github.com/precice/fenics-adapter/issues/1

And a testcase here:

AFAIK, there is still some implementation or testing missing for parallel 3D cases. Any feedback or testing is very welcome.
