Importing STL as Solid body

[tiwwexx]

Hello,

Simple question but hard to find the solution. When importing an STL file via model.Import(filepath), it imports as a triangle mesh. However, when I do this import manually I get an options box that pops up asking if I want to import as a solid body. Is there some option or flag I can use during the import python line that looks something like Import(filename, asSolid=True)? The reason why I want to do this is because the surface current viewer in the analysis tab only works for solid bodies, not these mesh grid objects.

Thanks for the help!
