I found an example of aI found an example of a monopole array antenna, but importing vtkplotter.dolfin got an error when I ran the code
I think it is the version problem, but i do not how to solve it.
my dolfin version is 2019.2.0.dev0
Please add the code in plaintext with 3x` encapsulation, and Also the full trace of your error messagw

Well, your error message relates to
Ie you mesh file does not exist.
This has nothing to do with vtkplotter.
Please reduce the code to a minimal reproducible example and use 3x` encapsulation, ie
```python
# add code here
```
This is strange, I put the grid file under the same folder, but it was not detected
That is an .msh file, not .xdmf file. You Need to convert your mesh
There is already code in the code to convert the.msh file, and it is this code that has the problem

Then your h5py installation is not successful.
Iâve fixed the h5py issue and now itâs back to my original question, I canât install the vtkplotteră
I installed the module with the command
pip install vtkplotter
or
pip3 install vtkplotter
The error are the same
ERROR: Could not find a version that satisfies the requirement vtkplotter (from versions: none)
ERROR: No matching distribution found for vtkplotter
when I use this command
sudo apt-get python3-vtkplotter
the error is
There is no package available for python3-vtkplotter, but it is referenced by other packages.
This could mean that the missing package may have been discarded,
Or it can only be found in other publishing sources
However, the following packages will replace it:
python3-vedo.
then i install vedo ,but the erorr still exist
As far as I can recall vtkplotter was renamed vedo, thus you have to change the import statement to import vedo if you have installed GitHub - marcomusy/vedo: A python module for scientific analysis of 3D data based on VTK and Numpy
Maybe @marcomusy can comment?
This is a lower version of the code, now that vtkplotter has been recall vedo, I think the datadir in the import vtkplotter has also changed, but I donât know what the datdir has been changed to.

This is very confusing⊠you seem to have a very old installation of vedo try:
pip uninstall vedo
pip install vedo -U

I reinstalled vedo2023.4.6 but as I said before cannot import name 'datadir
Traceback (most recent call last):

ImportError: cannot import name 'datadir' from 'vedo.dolfin' (/home/sohar/.local/lib/python3.10/site-packages/vedo/dolfin.py)
There is no datadir in vedo2023.4.6, it does not exist, this means that there is something else going wrong in your environment, unrelated to vedo or dolfinâŠ
Sorry for not replying to you immediately. I delet datadir, .msh file was successfully convert to .xdmf file, but the operation results can not converge. I find that dolfinx and dolfin2019.2 are downloaded on my virtual machine. Since the code writer used dolfin2019.2, I successfully run the code in the dolfin2019.2 environment and get the result.
