Licensing Timeout when Launching #2702

Hello,
I've recently had an issue (had to reinstall ANSYS' academic license on my computer) where I'm unable to launch mapdl in Python (previously had no issues). I'm using a VPN since I'm working off campus and the ANSYS license only works when connected to the university's IP.
Here is the code:

from ansys.mapdl.core import launch_mapdl
from ansys.mapdl.core import launcher
mapdl = launch_mapdl(exec_file='C:\Program Files\ANSYS Inc\v222\ansys\bin\winx64\ANSYS222.exe', override=True)

and here is the error:

C:\Program Files\ANSYS Inc\v222\ansys\bin\winx64\ansys222.exe
PyMAPDL is taking longer than expected to connect to an MAPDL session.

Hi @ay8tb & @germa89
So first this is not a crash - a crash is an unexpected closing of the program. Trying to run MAPDL in a working directory that has a lock file will result in MAPDL shutting down and this is expected behavior.

My gut tells me that when you installed the Ansys products you did not right-click the setup.exe and chose to run as an admin. MS User Account Control [UAC] can mess with installs even when using a admin account by limiting the admin account permissions during install. So please run the uninstall [C:\Program Files\ANSYS Inc\v222\Uninstall.exe] by right clicking Uninstall.exe and run that. Then redo the installation being sure to right-click setup.exe and run as …

well... maybe your last reinstallation broke the env vars (check AWP_ROOT env var), does it correspond ot the right version of MAPDL?

Try to launch MAPDL through the CLI. In your case something like:

cd %temporary_directory_you_can_fill_with_garbage%
C:\Program Files\ANSYS Inc\v222\ansys\bin\winx64\ANSYS222.exe

And see what you get.

It will be nice also if you can also post here the result of this:

You are using an old PyMAPDL version, please do update and we can start from it.

Also, try to run MAPDL through the command line please (the below is not 100% tested commands):

cd %temporary_directory_you_can_fill_with_garbage%
C:\Program Files\ANSYS Inc\v222\ansys\bin\winx64\ANSYS222.exe

Running from the Command Line opened and crashed it. When I run the .exe file as an administrator I have no issues.

Running from the Command Line opened and crashed it.

Didn't it show any useful message?

I'm surprised it worked using admin rights.... that's weird. Pinging @mikerife

No errors. The windows for MAPDL open and then close.
When I run it in admin, this is the error I get (it still opens though)
`
*** ERROR ***
Another ANSYS job with the same job name (file) is already running in this
directory or the file.lock file has not been deleted from an abnormally
terminated ANSYS run. To disable this check, set the ANSYS_LOCK environment
variable to OFF.

Do you wish to override this lock and continue (y or n)?
`
As well as this error:

I also get the error for file2.out and file3.out. The program then crashes.

Next check the TEMP and TMP environment variables. They should be set to something reasonable like
C:\Users<username>\AppData\Local\Temp Make sure that they are not set to a MS OS system folder or any other installed program folder. Or not defined at all.

Then try to run PyMAPDL (using a new terminal so that it picks up any changed environment variable). Now what happens?

Hi @mikerife,
I've gone ahead and done all the steps except for the TEMP and TMP environment variables (how would I do that?)
Tried to run PyMAPDL, still getting the same issue:

Had the same issue above executing ANSYS222.exe from the terminal.

Hi @ay8tb You can check the TEMP and TMP environment variables serveral ways; why not just echo them from a command window. Like this

And what does it return? Then do %temp%

ay8tb Feb 1, 2024

This is the result I get.
Edited because I realized I posted a Powershell line and not Command Prompt.

Hi @ay8tb
Ok, let's attack this from another angle. Create a folder to be used as the MAPDL working directory. Say C:\WorkingFolder Then open a DOS command window; cd to that working directory folder; and enter the following:

"C:/Program Files/ANSYS Inc/v222/ansys/bin/winx64/ANSYS222.exe -grpc"

Don't forget the double quotes. MAPDL should start up in aaS mode and just show a dos terminal window that will look someting like this:

If this starts up then note the Port number; 50052 is the default. If it does start up then open a new dos terminal and start Python. Then enter the two commands:

from ansys.mapdl.core import Mapdl
mapdl = Mapdl()

If the port number is not 50052 then instead use

from ansys.mapdl.core import Mapdl
mapdl = Mapdl(port=nnnn)

Where nnnn is the port number given in the MAPDL aaS start up window. If all this works you can then exit out of MAPDL by issueing the standard:

mapdl.exit()

Then quit() out of Python. If not, then show us what went wrong (error message etc).

Hi @germa89.
That worked when I ran it in a different location. Is there any way to bypass
C:\Program Files\ANSYS2\ANSYS Inc\v222\ansys\bin\winx64\ANSYS222.exe -dir C:\path\to\my\new\dir -grpc and then this to run pyMAPDL? Because doing that means I don't get any output in the Pycharm (my IDE) window which I need to utilize.

Hi @germa89 and @mikerife,
Just wanted to follow up. Thank you!

germa89 Feb 22, 2024

I'm not sure I follow... bypass what? and then PyMAPDL to run that line?

If it worked in a different location, you need to make sure you run every time in an empty directory.

Hi @germa89,

Sorry about the confusion. What I mean is that how can I run pyMAPDL in Python by directly writing
pymapdl.change_default_ansys_path('C:\\Program Files\\ANSYS2\\ANSYS Inc\\v222\\ansys\\bin\\winx64\\ANSYS222.exe') mapdl = launch_mapdl(start_instance=False, port=50052)

By running
C:\Program Files\ANSYS2\ANSYS Inc\v222\ansys\bin\winx64\ANSYS222.exe -dir C:\path\to\my\new\dir -grpc
and then starting pymapdl
'from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl(start_instance=False, port=50052)`
I am unable to get any outputs/print statements that I usually see when I run a Python IDE and what I need for my research.

mikerife Feb 23, 2024

@ay8tb launch_mapdl launches the MAPDL as a service instance; since you have already launched MAPDL aaS you need to connect to it from PyMAPDL. See the "Connect to a gRPC session" section of the doc here https://mapdl.docs.pyansys.com/version/0.67/getting_started/running_mapdl.html
