Description of the bug

I have used the following command snippet to run pymapdl:

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

but it is showing an entry point error every time and it does not start.

Steps To Reproduce

Hi @FiniteShekhar

It seems you have a problem with the license:

LicenseServerConnectionError: Exceeded 10 seconds while waiting for C:\Users\Shekhar Srivastava\AppData\Local\Temp\.ansys\licdebug.DESKTOP-N96VMAF.FEAT_ANSYS.222.out to exist.

Can you check you can run MAPDL using the Mechanical Launcher?

FiniteShekhar commented 2 years ago

Hello Thanks for your reply.

I have installed Ansys student. Also, I have checked and the mapdl is working perfectly fine.

I don't know why there is a license error.

Can you post here the result of the following python code:

from ansys.mapdl.core import Report
print(Report())

Also, can you try to run the following code in a terminal/windows shell:

& 'C:\Program Files\ANSYS Inc\v212\ansys\bin\winx64\ANSYS212.exe' -grpc

or in Linux:

/ansys_inc/v212/ansys/bin/ANSYS212.exe -grpc

Replace the path with your ANSYS installation path.

I see you are using an old version of Reader.

Can you upgrade the reader package (ansys-mapdl-reader)??

It seems you don't have licenses?

But with license_server_check=False it does work.

FiniteShekhar commented 2 years ago

But I am using Ansys Student Version. Does it not have license?

germa89 commented 2 years ago

I'm not 100% sure, but maybe the license in the student version is embedded. Hence the license check is bound to fail.

FiniteShekhar commented 2 years ago

how can I get it working?

germa89 commented 2 years ago

It seems it works if you use license_server_check.

Hence, until we fix this in the next release, just use:

from ansys.mapdl.core import launch_mapdl

mapdl = launch_mapdl(
    exec_file=r"C:\Program Files\ANSYS Inc\ANSYS Student\v222\ANSYS\bin\winx64\ANSYS222.exe", 
    additional_switches="-smp", # this might not be needed
    license_server_check = False
)

FiniteShekhar commented 2 years ago

Okie will keep it posted here if it works. Try to fix it further.
