Import .sat data in PyMAPDL

[herttim]

Hello,
just a basic question from my side.
I would like to import a .sat file into pymapdl by using the following code:

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

bearing_file = "C:/Users/HertingerT/OneDrive-SAF-HOLLANDGmbH/Desktop/GestufteLagerung/33213.sat"

mapdl.aux15()

mapdl.satin(name="bearing", extension=".sat" ,path=bearing_file, entity="ALL", fmt="1")
print(mapdl.geometry)
mapdl.vplot(vtk=True)

mapdl.exit()`

However, the output looks like that:
`MAPDL Selected Geometry
Keypoints: 0
Lines: 0
Areas: 0
Volumes: 0

C:\Users\HertingerT\AppData\Local\anaconda3\lib\site-packages\ansys\mapdl\core\mapdl.py:1529: UserWarning: Either no volumes have been selected or there is nothing to plot.
warnings.warn(`

Is there a problem with the file path or the general CAD model?

Thank you,
herttim

Hello!

Can you share the SAT file?

Kind regards,

[herttim]

@germa89 Here is the file:
33213.zip

[germa89]

Thank you for that!

Btw, did you try to use the standard ANSYS GUI and see if it works??

Hi @herttim & @germa89
There are a few things wrong with the command listing:

1 SATIN is not a AUX15 command
2 The file path should not include the file name, since it is given in the command, and it needs to be enclosed in single quotes.
3 The fmt value is a number and so should not be enclosed in quotes.
4 Is the file name bearing or 33213. Assuming 33213 as that is what is in the zip file.
5 The extension does not need a period
6 Not necessarily a problem but watch out for files on MS OneDrive. OneDrive can cause problems with file access if it wants to scan and/or backup a file.

So then this:

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

bearing_file = r"'C:/Users/HertingerT/OneDrive-SAF-HOLLANDGmbH/Desktop/GestufteLagerung/'"

mapdl.satin(name="33213", extension="sat" ,path=bearing_file, entity="ALL", fmt=1)
print(mapdl.geometry)

Hi @mikerife even with those recommendations, I still get the errors, see: #2286 (comment)

[germa89]

I also have troubles to read in that geometry

Why is the file name aa33213?

[germa89]

I renamed it to make sure it wasn't something with the file name.

@germa89 @herttim
I had to change the fmt to 0 in order for the import to create the volumes. If left at 1 the volumes are not created but the areas on down are:

[herttim]

@mikerife @germa89 Thanks for your help, the import is working now!
But it is still not possible to plot the volumes. It takes so many time to plot that the MAPDL server connection terminates.

Is there a reason for that? The CAD model shouldn´t be so big?!

[germa89]

Interesting, I did try without fmt (which then by default is 0) and I still had issues. @mikerife Can you send me your script? Also which version of MAPDL are you using?

[germa89]

@herttim Well... PyMAPDL is still not great at the plotting part. It is quite slow on transferring the geometry. Once I get it working on my machine, I will try to benchmark it and let you know.
