mapdl.cdread() doesn't seem to work, when cdb file directory is specified via mapdl.cwd()

I am trying to do read a cdb file using mapdl.cdread() and provided the working directory via mapdl.cwd(). However, I get some errors.

Here are the commands I have used:

from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl(exec_file='C:\\Program Files\\ANSYS Inc\\v212\\ansys\\bin\\winx64\\ansys212.exe', loglevel='ERROR',additional_switches='-smp',nproc=2)
mapdl.cwd(r'D:\AKD\PyANSYS\issues\cdb')
mapdl.prep7()
mapdl.cdread('db',fname='test',ext='db')

Errors I get:

Traceback (most recent call last):
  File "C:/Users/rgpatchi/PycharmProjects/pythonProject/venv/issue_rst_testing.py", line 10, in <module>
    mapdl.cdread('db',fname='test',ext='db')
  File "C:\Users\rgpatchi\PycharmProjects\pythonProject\venv\lib\site-packages\ansys\mapdl\core\mapdl_grpc.py", line 933, in cdread
    fname = kwargs.get('fname', args[1])
IndexError: tuple index out of range

I was able to workaround this issue using the below code.

import os
from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl(exec_file='C:\\Program Files\\ANSYS Inc\\v212\\ansys\\bin\\winx64\\ansys212.exe', loglevel='ERROR',additional_switches='-smp',nproc=2)
mapdl.cwd(r'D:\AKD\PyANSYS\issues\cdb')

my_path = r'D:\AKD\PyANSYS\issues\cdb'
my_file = os.path.join(my_path,'test.cdb')

mapdl.prep7()
#mapdl.cdread('db',fname='test',ext='db')
mapdl.cdread('db',my_file,'cdb')

mapdl.eplot()

Is this a bug?

Hi @RGPATCHI

Indeed this is a bug. Python checks if the file exists, but it checks in the python execution directory, not in the Mapdl directory (changed by cwd).

As you realized, input the full path to cdread fixes the issue.

I will look into this to be fixed in future releases. Thank you!

Hi @mcMunich ! Feel free to create another issue and post some example code we can replicate. Regards,
