I imported a .stl generated through a MATLAB program for topology optimization and into ABAQUS for further analysis. I am trying to create geometry from the orphan mesh using the "Create Geometry from mesh" plug-in readily available. This plug-in works well for most applications, but while I use the same plug-in, I am facing an error as seen in the figure attached below. It returns a number saying it does not exist.

1. Can someone please guide me on what this error could mean?

2. Are there any other useful file formats that can used to generate a part in MATLAB to be further analysed in ABAQUS?
