Stl Reader from Mac has Problems Reading Files from Cyclone PIC 3D Case

Hi, im using the Software for an uni Project. Unfortunately I got Problems reading the stl files of the tutorial Case PIC 3D cyclone with my Mac OS. when I open the new file with the case I get this error.

qt.qpa.fonts: Populating font family aliases took 171 ms. Replace uses of missing font family “.AppleSystemUIFont” with one that exists to avoid this cost.

when I start the simulation I get a Warning but the Stl data can be read but I think it is only one dimension read

this is the Warning that I get Warning: UNABLE TO PROPAGATE F_AT ARRAY FROM myPE=. 0
THIS USUALLY INDICATE A RANK WITH NO ACTIVE CELL
YOU MAY NEED TO ADJUST THE GRID PARTITIONING
TO GET BETTER LOAD_BALANCE.

and the Simulation needs Ages to and can’t even calculate 1 time Step
what can I do ? thanks

Ps: i also Can’t open the Stl data in Paraview

Is it an ASCII or binary STL file? Can you upload it here?

geometry.stl (12.4 MB)

Thank u for ur help

Looking carefully at the error messages:

STLReader: error while reading file geometry.stl at line 4: Parse error reading STL vertex

Sometimes the important messages are buried in a flood of other junk (in a better world this wouldn’t happen), but this is telling us the problem is at line 4 of geometry.stl

And that line is

     4	   vertex -0,015102040953934193 0,11660377681255341 -0,058056432753801346

Note you have commas instead of decimal points. This is probably a result of your locale settings. Try setting the environment variable LC_NUMERIC to C before generating the STL.

You should be able to repair this file without regenerating by doing:

$ sed -i s/,/./g geometry.stl

By the way, where did this file come from? The file distributed with the tutorial does not have commas.
