Before submitting the issue

Description of the bug

Hi, the previous ANSYS version i used is ANSYS 2022 R11, currently still installed in my pc. The pyansys dpf core is able to run with no issue previously. After installing ANSYS 2023 R2, I encounter dpfserverexception error even with simple demo example.

Steps To Reproduce

  1. Install ANSYS 2023 R2

  2. open command prompt

  3. open python environment by entering "python"

  4. run a simple demo example:

    >>> from ansys.dpf.core import Model
>>> from ansys.dpf.core import examples
>>> model = Model(examples.find_simple_bar())
>>> print(model)

  5. Following error shows after entering "print(model)"

Hi, the way i got it work is:

  1. Uninstall ANSYS 2023R2
  2. Uninstall Python
  3. Reinstall Python
  4. Reinstall ANSYS 2023R2

Although not 100% sure, I believe the error has something to do with the python library where ansys-dpf-core is installed. FYI, you can find where the module is install when you redo the "pip install ansys-dpf-core".

Hi @junming1202, Not sure what the error could have been, but I am glad this is now working.

I am having exactly the same issue after upgrading from 2023R1 to 2024R1 on a Linux machine. Can't reinstall so easily due to extensive RSM configuration. Would be nice to get a better solution.

I use virtual environments for Python so that is a bit different than OP.

tagging @PProfizi for visibility as this issue is closed.

Hi @aukselis-c1connections, Looking back at the issue I can see that OP had some out-of-date libraries in his environment which could prevent PyDPF from working properly with ANSYS2023 R2. Could you please share a pip list? You can find more information on server-client compatibility here.
