I have two different mesh files (both are .inp files obtained from Abaqus) that represent the exact same geometries with the same boundary conditions, etc. The only difference is that one of them is meshed in a structured fashion and the other one is meshed in an unstructured way.
Now here is my question, how do I find out which file contains the structured mesh and which one contains the unstructured one? Of course, I mean apart from visualizing the files and trying to zoom in on the meshes and see if they look structured or unstructured.
What should I do in such situation in general? What is the "scientific" way to figure out the answer and avoid visualizing the mesh?
