CAD readers will not be found without the AWP env var. The Fluent-specific env var you are using doesn't resolve that because the CAD readers are outside Fluent. Your AWP env var would point to /usr/ansys_inc/v231. Does that not work?

schrummy14 commented 1 year ago

Hello, Correct, the AWP variable does not work when installing via pip install pyansys[all] (installs pyfluent 0.11)

I have tried using only the pyfluent install with visualization and parametric. Here the AWP variable works but I get the same error.

The other two examples did run without issue.

Please let me know if there is anything you would like me to pull from the install environment. I will be out next week.

dnwillia-work commented 1 year ago

When you log in to your running container and spin up a virtual environment what's the value, or values, of AWP_ROOT<ver> you have configured? These need to be set in the running environment. It's documented on the README page:

https://github.com/pyansys/pyfluent#launching-fluent

I don't know why we documented this PYFLUENT_FLUENT_ROOT variable, probably the language there that says "or set ..." should be removed or just remove the documentation entirely. This variable is meant for internal development so that developers working on the server code can point PyFluent at a local Fluent build. I'd actually leave this unset entirely and just stick with AWP_ROOT<ver>

schrummy14 commented 1 year ago

Hello, I have tried the following: export AWP_ROOT231=/ansys_inc/v231 (which is a sym link to /usr/ansys_inc/v231) export AWP_ROOT231=/usr/ansys_inc/v231

Does this need to be set before ansys is installed?

seanpearsonuk commented 1 year ago

No, typically it would not be set before installation. On Windows, the installer sets it for you, while on Linux, it's a manual step that can be completed afterwards.

schrummy14 commented 1 year ago

That's what I figured as everything else has been working so far. I use a script to start my Jupyter notebook and before Jupyter starts, I set the AWP_ROOT231 variable as above.

schrummy14 commented 1 year ago

Is there anything else you would like me to provide or test?

schrummy14 commented 1 year ago

Hello, I have tried again using 232 and am getting the same issue with the mixing elbow example. https://fluent.docs.pyansys.com/version/stable/examples/00-fluent/mixing_elbow.html

sh: 1: /usr/ansys_inc/v232/commonfiles/CPython/3_10/linx64/Release/Ansys/TGrid/runCADReaders.csh: not found
schrummy14 commented 1 year ago

I am using the AWP_ROOT environment variable.

export AWP_ROOT232=/usr/ansys_inc/v232

I am now using Ubuntu 20.04 instead of CentOS 7.

Problem has been solved. On Ubuntu 20.04 (haven't tested for RHEL based OSs nor newer versions of Ubuntu), you need to install the tcsh package. This package is missing from the Ansys installation docs.
