Description of the bug

When trying to read an *.IGES file from a path with white spaces, it falls over with the following error message:

Traceback (most recent call last):
  File "D:\proj\main.py", line 22, in <module>
    mapdl.igesin(cad_file,'IGS')

Process finished with exit code 1

When reading the IGES file from a path without white spaces, it works fine. in the APDL GUI, it can read iges files from paths containing white spaces.

Steps To Reproduce

Steps:

Place the IGES file attached in this report in a path without whitespaces and run. It should result in a viewer with two cylindrical faces.
Now, place the IGES file in a path with whitespaces and update the directory variable accordingly. The error message above should point to the directory variable, sans whitespaces.

Code in question:

import os

iges = "test.igs"

mapdl = launch_mapdl()
mapdl.clear()
mapdl.aux15()
directory = r'D:\Some\Path\With\White Spaces'
cad_file = os.path.join(directory, iges)
mapdl.igesin(cad_file)
print(mapdl.geometry)
mapdl.aplot('all')
mapdl.exit()

Hi @aravantaa

Thank you very much for posting this very well detailed, explained and formatted issue. We appreciate a lot your support.

It seems it is an MAPDL error.

Pinging @FredAns for visibility.

I might be able to do something on the client side to mitigate this issue.

Kind regards,

germa89 commented 1 year ago

Surprisingly, in MAPDL you can do this:


IOPTN,IGES,SMOOTH   
IOPTN,MERGE,YES 
IOPTN,SOLID,YES 
IOPTN,SMALL,YES 
IOPTN,GTOLER, DEFA  
IGESIN,'test','igs','..\other path with spaces\'

And it works. But the third argument of IGESIN is not documented.

Hi @aravantaa, @germa89, & @FredAns Here is a way to do this with utilizing the PyMAPDL input_strings method and some Python replacing. I created a folder with some spaces in it and am using it as the Python (Jupyter Lab) and MAPDL working directory.

from ansys.mapdl.core import launch_mapdl
import os
path = os.getcwd()
mapdl = launch_mapdl(run_location = path)
iges = "test.igs"
cad_file = os.path.join(path, iges)
print(cad_file)

The cad_file value is D:\TechnicalSupport\PyMAPDL\1601\Folder With White Space\test.igs Then the input continues with:

mapdl.clear()

cmd = '''
*dim,iges_file,string,248
*set,iges_file(1),'QQQ'
'''.replace("QQQ",cad_file)

mapdl.input_strings(cmd)

mapdl.aux15()
mapdl.igesin('iges_file(1)')
mapdl.prep7()
print(mapdl.geometry)
mapdl.aplot('all')

And the resulting geometry:

I tried different options on the MPADL Iges import but there is a bad surface/area and the volume cannot be auto created.

@mikerife Thank you for the workaround Mike. It works fine on my end as well (pyCharm). Good idea to inject the apdl commands. @germa89 Yes, I also suspected a limitation with APDL at first, but when I could read in the IGES like you describe, I figured that was not the case.

Awesome @mikerife ! I could implement that trick on PyMAPDL. :)

Thank you!

aravantaa commented 1 year ago

@germa89 any chance for a bug fix for this? thanks!

germa89 commented 1 year ago

Not for the moment unfortunately. :(

aravantaa commented 1 year ago

@germa89 Thanks for the follow up. We have a workaround that works fine for now. Cheers!
