Aspect ratio is the measure of a mesh element's deviation from having all sides of equal length. A high aspect ratio occurs with long, thin elements. Entering an overly large value for the Minimum Element Size mesh control may cause the mesh generator to create solid elements with high aspect ratios.

Creo Simulate calculates aspect ratio, R, according to this formula:

R = E/h

where E is the longest edge and h is the shortest height—the distance between a vertex and the opposite surface or edge.
