Cannot use examples for DPF-Core or DPF-Post

[pmaroneh]

DPF-Core and DPF-Post packages are correctly installed and the examples files can be found in the installation directory.
However when trying to use these examples, an error message is returned about the files not being found. It actually seems that the dpf server is not starting:

• DPF-Post example:
  
  - DPF-Core example:

As it turns out, the dpf modules have been upgraded to v3.0 and these are only compatible with version 2021R2 of Ansys. This release has been made available for download here:

Adding a verification of the Ansys version used and providing appropriate recommendation about version of DPF to be installed such as:
pip install ansys.dpf.core==0.2.1
would be great though.
