I have errors when importing .stl files. The error is:
"could not match up all facet edges"
This error message means that there are too large "gaps" between the facets in your stl file resulting in a "non-watertight" geometry (mesh generators require "watertight" geometries with no gaps as input). Please see the following section in the documentation for reference:
To fix this you can possibly try to re-generate the stl file from the original data with a higher tolerance. Alternatively, FEATool Multiphysics (not available with CFDTool) includes a MATLAB function that can be used to try basic mesh repair:
