Hello,
How to create zero length elements (which is an element between two points having the same geometrical location) in GiD?
kindly advise
you can create two different points in exactly the same x,y,z location, and create a line between them (a zero length line)
and you can generate a mesh.
GiD will generate a zero length element that in general is wrong, but could be appropriated in some cases
e.g. for contact elements.
Be careful to not invoke a collapse of the geometry, then the points will be joined and the line deleted.
