# Searching for Distorted Mesh Elements

A distorted mesh element is a distorted (high aspect ratio) triangle. Distorted mesh elements can result in decreased accuracy of the results and could lead to poor convergence for iterative solvers.

The Solver does not directly search for distorted mesh
elements, but the consequence of distorted mesh elements is that the condition
number for the method of moment (MoM) matrix increases.

Note: The Solver will give a warning or error the condition
number becomes too high.

Distorted mesh elements are specified in terms of the minimum internal angle. In an ideal mesh, all internal angles are 60° (but this rarely possible). If any of the three angles in a mesh element are very small, the element is a sliver. Such elements can be removed by deleting vertices.
