license checkout failed

[Spclaim]

Hi,
I setup the docker image according to the documentation. But during startup of the container I receive the message License checkout failed.

When I try to run a python demo script from the documentation I receive the following error.

ansys.geometry.core.errors.GeometryExitedError: Geometry service connection terminated: Exception was thrown by handler.

Unclear if the license checkout is root cause of the thrown python error

help would be appreciated.

Hi @Spclaim - could you please share with us the docker run command and the docker container logs that you get?

You can hide out the license server IP/DNS for security purposes, for sure =)

[RobPasMue]

You should have a Discovery/SpaceClaim license - otherwise it will not work. Sorry, should have clarified this before

[Spclaim]

We can use Spaceclaim / Discovery because it is included in the mechanical enterprise license. I was under the assumption that this is sufficient and we do not need an extra license only valid for spaceclaim / discovery. Sorry for the confusion. This is a bit counter-intuitive.

[RobPasMue]

Let me check with the team and get back to you. I am not sure of the details inside the licensing check.

[RobPasMue]

Before anything else...

• Did you try passing in the --dns="8.8.8.8" flag? Did this work?

I have received confirmation that the Ansys Mechanical Enterprise license is not sufficient to use the Ansys Geometry Service. However, you are saying that you have access to both SpaceClaim and Discovery so, let's do another trial:

• Do you have Ansys 23R2 SP1? If that's the case, continue to the next step. Otherwise, you will need to install it.

• Let's try running PyAnsys Geometry against SpaceClaim and Discovery. Bear in mind that interaction with Discovery is limited (you will only be able to launch Discovery with ansys-geometry-core==0.3.2. Starting on 24R1 you will be able to perform all operations. In 23R2 SP1 you can perform most operations with SpaceClaim though:

  • Launch SC from PyAnsys Geometry

    from ansys.geometry.core import launch_modeler_with_spaceclaim
    
    modeler = launch_modeler_with_spaceclaim()
    print(modeler)

  • Launch Discovery from PyAnsys Geometry

    from ansys.geometry.core import launch_modeler_with_discovery
    
    modeler = launch_modeler_with_discovery()
    print(modeler)

Your Ansys products should start fine if your license is valid. Let's try verifying it.

You may find more information on how to launch the local installation of Ansys SpaceClaim and Discovery here: https://geometry.docs.pyansys.com/version/0.3/getting_started/local/index.html

[Spclaim]

Hi thank you, no dns 8.8.8.8 is not reachable from company network. We have our own DNS server, but this also didn’t work. I have 23R2 not sure about SP1. But I can start both SC and Discovery from python. Only issue is that I must close it manually.

[RobPasMue]

Okay, could you try running some of the online examples for PyAnsys Geometry and see if they work?

Also, if you run

modeler.close()

Do you still have to close it manually?

[RobPasMue]

You will have to run an actual modelling example. For example: https://geometry.docs.pyansys.com/version/0.3/examples/02_sketching/dynamic_sketch_plane.html

[Spclaim]

Really appreciate your help.

modeler.close() works properly .

the sketch tutorial worked with a pyvista plot of the created sketch. nice.

the parametric gear sketch does not work and the single body with material assignment also does not work.

Hi @Spclaim - yes, support for SpaceClaim and Discovery from PyAnsys Geometry, at least on 23R2 is limited. Certain operations might fail. The intended way to operate with PyAnsys Geometry is against the Ansys Geometry Service. Support will be improved starting on 24R1 and we will try to make most of our APIs compatible with the Ansys standalone products.

[RobPasMue]

Just to be clear - all PyAnsys Geometry APIs will work against the Ansys Geometry Service binaries you found on the release. But we do not ensure that all APIs work against the Ansys standalone products on 23R2.

[RobPasMue]

After further investigation we have reached the main issue on the licensing - the Ansys Geometry Service (headless and dockerized solution) only works with a Discovery Modeling license. If you have an Ansys Mechanical Enterprise license, for example, you will be able to use PyAnsys Geometry with SpaceClaim or Discovery, but not the Ansys Geometry Service.

On 23R2 SP1 it will only work with SpaceClaim due to some issues with Discovery. Also, support to Ansys standalone products (SpaceClaim, Discovery) is limited from the PyAnsys Geometry API. Certain operations might fail since the intended interaction of this library is with the Ansys Geometry Service directly.

Starting on 24R1, we will provide larger support for the Ansys standalone products (Discovery, SpaceClaim). For PyAnsys Geometry version compatibility with Ansys products please refer to https://geometry.docs.pyansys.com/version/stable/getting_started/compatibility.html

Thanks @Spclaim for opening this discussion. I will mark this response as an answer for future reference.

[RobPasMue]

We will transfer this discussion to the FAQ section in our documentation.
