This might be a simple question, but I can’t seem to find an answer on the internet that really explains the mistake in my project. I keep getting the error
"Sheet bodies detected.
The model contains sheet bodies (surface data). It is recommended to solidify all parts of the model as otherwise unexpected meshing behavior can appear.
What am I doing wrong (or not doing) that causes this issue? I created the CAD project in Onshape and would like to do some basic CFD on it (I have no experience in engineering, this is all just for fun).
