Producing Non-Conformal Mesh from .STEP import
I'm unsure if this is actually unexpected behaviour for the geometry in question or perhaps a mis-understanding/mis-implimentation on my part. I'm working with an embedded volume - the system represents a current loop embedded in a volume of air (the outer box) which should surround my current loop.
I'm working with an imported STEP file (attached). I have set the kernal to OCC first then merged the file as advised in the documentation. I then attempt to mesh via the GUI.
I would expect as is explained in the documentation the surfaces to be meshed first and the volume meshed afterwards with conformal elements to the various inner surfaces. What I'm finding happens is it meshes the surfaces correctly. It will then mesh inside the current loop correctly. The outer volume is also meshed, but it has large elements running to the origin which overlap the elements present inside the current loop. There are then overlapping elements making the mesh non-conformal.
The problem is a little clearer to interpret visually when I use a finer mesh and move to using the mesh inside MATLAB. See how larger elements seem to completely encompass the numerous elements inside the current loop rather than conforming to the surfaces
From the documentation I believe this maybe unexpected behaviour however this could be poor implementation on my part - any guidance in this case is greatly appreciated.
